Constants

EDGE_SUFFIX  : string = '_e'
The suffix used for edge fields in queries.
FIELDS  : string = 'fields'
The 'fields' key for initialization arrays.
JOIN_SUFFIX  : string = '_j'
The suffix used for join fields in queries.
SEARCHABLE  : string = 'searchable'
The 'searchable' parameter key.
UNIQUE_SUFFIX  : string = '_u'
The suffix used for unique fields in queries.
NORMALIZED_MARKERS  : array<string|int, mixed> = [\oihana\arango\enums\Field::ALTERS, \oihana\ar...
The scalar `Field::` markers copied **verbatim** from the raw field options into the normalized definition produced by {@see normalizeFieldDefinition()}.

Properties

$activable  : bool
$fields  : array<string, mixed>
The fields definitions to return in get/list methods.
$searchable  : array<string|int, mixed>|null
The searchable fields swept by the classic `?search=` `LIKE` (see {@see prepareSearch()}). A list of field names; an entry may instead be an array carrying its name under {@see Search::KEY} plus options such as {@see Search::REQUIRES} to gate the field by permission:
$searchOperator  : string
The default operator combining the words of a `?search=` term **within a field** during the classic `LIKE` sweep ({@see prepareSearch()}): {@see \oihana\arango\db\enums\Logic::AND} (every word must be found in the field, order-independent) or {@see \oihana\arango\db\enums\Logic::OR} (the whole term matched as one substring — the default, backward-compatible).
$searchSeparators  : string
The extra characters (beyond whitespace) that split a `?search=` term into words for the `AND` operator of the classic `LIKE` sweep ({@see prepareSearch()}).
$skinFields  : array<string, array<string, mixed>>
Optional per-skin alternative projections for the model's own fields.
$view  : array<string|int, mixed>|null
The model-level ArangoSearch declaration (`AQL::VIEW` block, see {@see Search}).

Methods

bind()  : string
Bind a value to an AQL query variable.
bindCollection()  : string
Bind a collection name to an AQL query variable.
bindView()  : string
Bind the model's declared View name (`AQL::VIEW` block, {@see Search::NAME}) to an AQL query variable — collection bind parameters (`@@view`) are valid for View names as well.
buildLastQuery()  : string
Build the AQL query to fetch the last document from the collection.
getViewLinks()  : array<string, ArangoSearchLink>
Returns the desired per-collection link map of the declared View — the model's collection linked with {@see buildViewLink()} — or an empty map when the model has no collection.
getViewName()  : string|null
Returns the name of the declared View ({@see Search::NAME} of the `AQL::VIEW` block), or `null` when the model declares none.
hasViewSearch()  : bool
Indicates whether the View search is active: the model declares a named View (`AQL::VIEW` block) with at least one searched field, **and** the request carries a non-empty search term.
initializeActivable()  : static
Initialize the activable flag to check if the documents are 'active' or not.
initializeFields()  : static
Initialize fields definitions from an associative array.
initializeSearchable()  : static
Initialize the 'searchable' property.
initializeSearchOperator()  : static
Initialize the `LIKE` sweep operator ({@see $searchOperator}) from the `Search::OPERATOR` init key. An explicit value is normalized to {@see Logic::AND} / {@see Logic::OR}; an absent key keeps the default ({@see Logic::OR}, backward-compatible).
initializeSearchSeparators()  : static
Initialize the `LIKE` sweep word separators ({@see $searchSeparators}) from the `Search::SEPARATORS` init key. Accepts a string of characters or a list of characters (joined to a string); an absent key keeps the default (the hyphen). Only meaningful with the `AND` operator. See {@see Search::SEPARATORS}.
initializeSkinFields()  : static
Initialize the per-skin projections registry from an associative array.
initializeView()  : static
Initialize the model-level ArangoSearch declaration (`AQL::VIEW` block) and lazily provision the View, mirroring the collection provisioning of `initializeCollection()`: when the model is lazy and the declared View does not exist, it is created from the declaration — the searched fields (dotted paths supported) are linked on the model's collection with the declared {@see Search::ANALYZER}. An existing View is never altered — inspect and resynchronize explicitly with {@see viewDiff()} / {@see viewSync()} (or the `views` action of the `arangodb` command).
prepareActive()  : string|null
Prepare the 'active' variable.
prepareQueryFields()  : array<string, array<string|int, mixed>>|null
Prepares query fields based on internal definitions and optional skin filter.
prepareSearch()  : string|null
Prepare the searchable AQL conditions — the classic `?search=` `LIKE` sweep, a parenthesized `OR` of case-insensitive `LIKE()` predicates over every (permitted) searchable field, used when no View search is active.
prepareViewSearch()  : string|null
Prepare the relevance-ranked `SEARCH` expression of an active View search, or `null` when the View search is inactive (no `AQL::VIEW` declaration, no searched fields, or no search term) — the caller then falls back to the classic `LIKE` sweep of {@see prepareSearch()}.
returnFields()  : string
Generates an AQL document expression or LET statement with the selected fields.
viewDiff()  : DiffReport
Compares the model's View declaration with the server state and reports the differences, without touching anything.
viewSync()  : DiffReport
Reconciles the model's View with its declaration: creates it when missing, repairs a drift with `updateProperties()` (the View stays available while the inverted index rebuilds in the background), and leaves {@see DiffStatus::IN_SYNC}, {@see DiffStatus::INVALID} or {@see DiffStatus::UNREACHABLE} reports untouched.
buildViewLink()  : ArangoSearchLink
Builds the View link of the model's collection from the `AQL::VIEW` declaration: every searched field (dotted paths become nested fields) is indexed with its resolved Analyzer — the per-field {@see Search::ANALYZER} when declared, otherwise the View-level one.
buildViewSearchGroups()  : array<string, array<string|int, string>>
Builds the per-Analyzer expression groups of the View search under the historical `OR` grammar : each comma-separated term is bound whole and matched in one shot per field (`doc.<field> IN TOKENS(@search_N, …)`, whose `IN` semantics already `OR` the term's tokens), plus the optional phrase and fuzzy branches. This is the exact grammar emitted when no field opts into {@see Search::OPERATOR} `AND` — see {@see prepareViewSearch()}.
buildViewSearchGroupsWithOperator()  : array<string, array<string|int, string>>
Builds the per-Analyzer expression groups when at least one field opts into {@see Search::OPERATOR} `AND`. Each comma-separated term is split into words (whitespace) ; a field then combines those words with its resolved operator :
getSearchableSpecs()  : array<string, array<string, mixed>>
Normalizes the model's `AQL::SEARCHABLE` list into a per-field specification map `field => [ (Search::REQUIRES => …)? ]`, the single source consumed by {@see prepareSearch()} (the `LIKE` sweep) and by the `searchable` fallback of {@see getViewFieldSpecs()}.
getViewFieldSpecs()  : array<string, array<string, mixed>>
Normalizes the searched fields of the `AQL::VIEW` declaration into a per-field specification map `field => [ Search::BOOST => float, … ]` — the single source of truth from which {@see getViewSearchFields()} derives the boost map and {@see prepareViewSearch()} resolves the per-field options.
getViewSearchFields()  : array<string, float>
Normalizes the searched fields into a `field => boost` map — a boost-only façade over {@see getViewFieldSpecs()}, used by {@see buildViewLink()} and {@see viewDiff()} which only care about the field paths and their weights.
ngramMatch()  : string
Builds the `NGRAM_MATCH(doc.<field>, @term [, threshold], "<analyzer>")` core of a {@see Search::NGRAM} branch (without the surrounding boost). The threshold is inlined only when the field declares one, else the server default applies. Shared by the whole-term and the per-word emissions.
pushWholeTermField()  : void
Pushes the whole-term match of one field onto the Analyzer groups — the base `doc.<field> IN TOKENS(@term, …)` (boosted when the field weight is not `1`), the optional exact-phrase bonus and the optional fuzzy branch, plus the {@see Search::NGRAM} branch when declared. This is the `OR`-grammar emission, shared by {@see buildViewSearchGroups()} (every field) and by the `OR` fields of {@see buildViewSearchGroupsWithOperator()}.
resolveFieldSearchSpec()  : array{0: string[], 1: float, 2: int, 3: bool, 4: string}
Resolves the per-field search facets shared by both group builders : the Analyzers indexing the field (a per-field {@see Search::ANALYZER} overrides the View-level one, a single Analyzer normalized to a one-element list), the boost, the fuzzy tolerance and phrase bonus (a per-field value overrides the View-level default), and the `doc.<field>` accessor (with the `[*]` array marker stripped — the flat path already matches any element of the indexed array, and the `SEARCH` grammar rejects the expansion form).
splitSearchTermWords()  : array<string|int, string>
Splits an `AND`-operator search term into its words, on whitespace plus the given extra separator characters ({@see Search::SEPARATORS}). Whitespace always splits; `$separators` adds literal characters (a string, or a list of characters joined to one), `null` falls back to the hyphen default, and an empty value splits on whitespace only. The extra characters are regex-escaped, so any punctuation is safe. Empty words are dropped.
filterFieldsBySkin()  : array<string, mixed>
Filters fields based on an optional skin.
generateUniqueKey()  : string|null
Generates a unique key for special filters like edges, joins, or unique names.
normalizeFieldDefinition()  : array<string, mixed>|null
Normalize a field definition into a structured array for queries.

Constants

EDGE_SUFFIX

The suffix used for edge fields in queries.

public string EDGE_SUFFIX = '_e'

FIELDS

The 'fields' key for initialization arrays.

public string FIELDS = 'fields'

JOIN_SUFFIX

The suffix used for join fields in queries.

public string JOIN_SUFFIX = '_j'

SEARCHABLE

The 'searchable' parameter key.

public string SEARCHABLE = 'searchable'

UNIQUE_SUFFIX

The suffix used for unique fields in queries.

public string UNIQUE_SUFFIX = '_u'

NORMALIZED_MARKERS

The scalar `Field::` markers copied **verbatim** from the raw field options into the normalized definition produced by {@see normalizeFieldDefinition()}.

private array<string|int, mixed> NORMALIZED_MARKERS = [\oihana\arango\enums\Field::ALTERS, \oihana\arango\enums\Field::DEFAULT, \oihana\arango\enums\Field::ELSE, \oihana\arango\enums\Field::FORMAT, \oihana\arango\enums\Field::NAME, \oihana\arango\enums\Field::NULLABLE, \oihana\arango\enums\Field::PATH, \oihana\arango\enums\Field::PATHS, \oihana\arango\enums\Field::PROPERTY, \oihana\arango\enums\Field::QUOTED, \oihana\arango\enums\Field::RAW, \oihana\arango\enums\Field::REQUIRES, \oihana\arango\enums\Field::SELF_REQUIRES, \oihana\arango\enums\Field::SCOPE, \oihana\arango\enums\Field::WHEN, \oihana\arango\enums\Field::WHERE]

⚠️ Single source of truth — register every new marker here. A scalar Field:: marker absent from this list is silently stripped during projection normalization, so it never reaches the query builders nor the permission gates (this is exactly how Field::SELF_REQUIRES was first lost). The structural markers are built separately and must NOT be added here: Field::FILTER (seeded from the already-resolved filter), Field::FIELDS / Field::EDGES / Field::JOINS (sub-projections attached after the recursive walk), Field::UNIQUE (generated), and the skin buckets (AQL::SKIN_FIELDS).

Field::DEFAULT is intentionally kept even though it resolves to null (Field::DEFAULT === null), so the copy is byte-for-byte identical to the historical literal table.

Properties

$fields

The fields definitions to return in get/list methods.

public array<string, mixed> $fields = []

Keys are field names, values are either a Filter constant, a definition array, or null.

[
    Schema::ACTIVE                => Filter::BOOL ,

    Schema::NUM_PERMISSIONS       => Field::FILTER => Filter::EDGES_COUNT
] ;

$searchable

The searchable fields swept by the classic `?search=` `LIKE` (see {@see prepareSearch()}). A list of field names; an entry may instead be an array carrying its name under {@see Search::KEY} plus options such as {@see Search::REQUIRES} to gate the field by permission:

public array<string|int, mixed>|null $searchable = []
AQL::SEARCHABLE =>
[
    'name' ,                                                       // public
    [ Search::KEY => 'salary' , Search::REQUIRES => 'hr:salary' ], // gated
]

$searchOperator

The default operator combining the words of a `?search=` term **within a field** during the classic `LIKE` sweep ({@see prepareSearch()}): {@see \oihana\arango\db\enums\Logic::AND} (every word must be found in the field, order-independent) or {@see \oihana\arango\db\enums\Logic::OR} (the whole term matched as one substring — the default, backward-compatible).

public string $searchOperator = \oihana\arango\db\enums\Logic::OR

Set once per model through the Search::OPERATOR init key. The View search carries its own operator inside the AQL::VIEW block (per field), see Search::OPERATOR.

$searchSeparators

The extra characters (beyond whitespace) that split a `?search=` term into words for the `AND` operator of the classic `LIKE` sweep ({@see prepareSearch()}).

public string $searchSeparators = \oihana\enums\Char::HYPHEN

A string of characters; set once per model through the Search::SEPARATORS init key (a list of characters is normalized to a string at init). The default is the hyphen (-) so « Jean-Marc » splits like « Jean Marc »; an empty string keeps hyphenated codes whole. Only used in AND mode. See Search::SEPARATORS.

$skinFields

Optional per-skin alternative projections for the model's own fields.

public array<string, array<string, mixed>> $skinFields = []

A skin => fields table with the exact same semantics as the AQL::SKIN_FIELDS key of an edge/join definition : each bucket is a complete fields array (same shape as $fields), the resolution order is [$skin]['*']$fieldsnull, and the selected bucket fully replaces the others (no merging). An edge/join that declares no projection of its own inherits the target model's buckets, since it prepares the model fields with the request skin.

An empty registry (default) keeps the legacy single-projection behavior, byte-for-byte.

Tags
example
$model->skinFields =
[
    Skin::DEFAULT => [ Schema::NAME => Filter::DEFAULT ] ,
    Skin::FULL    => [ Schema::NAME => Filter::DEFAULT , Schema::ROLES => [ Field::FILTER => Filter::EDGES ] ] ,
] ;

$view

The model-level ArangoSearch declaration (`AQL::VIEW` block, see {@see Search}).

public array<string|int, mixed>|null $view = null

When present (with a Search::NAME), the ?search= parameter switches from the simple LIKE sweep to an index-accelerated, relevance-ranked SEARCH against the declared View.

bindView()

Bind the model's declared View name (`AQL::VIEW` block, {@see Search::NAME}) to an AQL query variable — collection bind parameters (`@@view`) are valid for View names as well.

public bindView([array<string|int, mixed> &$binds = [] ]) : string
Parameters
$binds : array<string|int, mixed> = []

Reference to the array of existing bind variables.

Tags
throws
BindException

buildLastQuery()

Build the AQL query to fetch the last document from the collection.

public buildLastQuery([array<string|int, mixed> $init = [] ][, array<string|int, mixed> &$bindVars = [] ]) : string

The query sorts the documents by a specific property (default: Schema::MODIFIED) in descending order and returns the first item.

Generated AQL structure: FOR doc IN @@collection SORT doc. DESC LIMIT 1 RETURN { ...fields }

Parameters

initializeActivable()

Initialize the activable flag to check if the documents are 'active' or not.

public initializeActivable([array<string|int, mixed> $init = [] ]) : static
Parameters

Return values
static

initializeFields()

Initialize fields definitions from an associative array.

public initializeFields([array<string, mixed> $init = [] ]) : static
Parameters
$init : array<string, mixed> = []

Optional initialization array containing a 'fields' key.

Return values
static

initializeSearchable()

Initialize the 'searchable' property.

public initializeSearchable([array<string|int, mixed> $init = [] ]) : static
Parameters
$init : array<string|int, mixed> = []
Return values
static

initializeSearchOperator()

Initialize the `LIKE` sweep operator ({@see $searchOperator}) from the `Search::OPERATOR` init key. An explicit value is normalized to {@see Logic::AND} / {@see Logic::OR}; an absent key keeps the default ({@see Logic::OR}, backward-compatible).

Return values
static

initializeSearchSeparators()

Initialize the `LIKE` sweep word separators ({@see $searchSeparators}) from the `Search::SEPARATORS` init key. Accepts a string of characters or a list of characters (joined to a string); an absent key keeps the default (the hyphen). Only meaningful with the `AND` operator. See {@see Search::SEPARATORS}.

public initializeSearchSeparators([array<string|int, mixed> $init = [] ]) : static
Parameters
$init : array<string|int, mixed> = []
Return values
static

initializeSkinFields()

Initialize the per-skin projections registry from an associative array.

public initializeSkinFields([array<string, mixed> $init = [] ]) : static
Parameters
$init : array<string, mixed> = []

Optional initialization array containing an AQL::SKIN_FIELDS key.

Return values
static

initializeView()

Initialize the model-level ArangoSearch declaration (`AQL::VIEW` block) and lazily provision the View, mirroring the collection provisioning of `initializeCollection()`: when the model is lazy and the declared View does not exist, it is created from the declaration — the searched fields (dotted paths supported) are linked on the model's collection with the declared {@see Search::ANALYZER}. An existing View is never altered — inspect and resynchronize explicitly with {@see viewDiff()} / {@see viewSync()} (or the `views` action of the `arangodb` command).

public initializeView([array<string|int, mixed> $init = [] ]) : static
Parameters
$init : array<string|int, mixed> = []

throws

prepareActive()

Prepare the 'active' variable.

public prepareActive([array<string|int, mixed> $init = [] ][, array<string|int, mixed>|null &$binds = null ][, string $docRef = AQL::DOC ]) : string|null
Parameters
$init : array<string|int, mixed> = []
$binds : array<string|int, mixed>|null = null
$docRef : string = AQL::DOC
Tags
throws
BindException
Return values
string|null

prepareQueryFields()

Prepares query fields based on internal definitions and optional skin filter.

public prepareQueryFields([array<string|int, mixed>|null $fields = null ][, string|null $skin = null ][, string|null $parentKey = null ][, string|array<string|int, mixed>|null $in = null ]) : array<string, array<string|int, mixed>>|null

Converts string filters to array format, applies skins, and normalizes each field. When $fields is null and the model declares a $skinFields registry, the projection is resolved per skin first ([$skin]['*']$fields — the same order as an edge/join AQL::SKIN_FIELDS). The skin filter applies at every nesting level : the sub-fields of a WRAP, DOCUMENT or MAP definition are prepared with the same skin, so a nested Field::SKINS marker is honored in depth. A structural field whose declared sub-fields are all removed by the skin — or whose own AQL::SKIN_FIELDS table resolves to nothing for the requested skin — is dropped from the result.

Parameters
$fields : array<string|int, mixed>|null = null

Optional custom fields to process (defaults to $this->fields).

$skin : string|null = null

Optional skin to filter applicable fields.

$parentKey : string|null = null

Optional parent key definition.

$in : string|array<string|int, mixed>|null = null

Optional field or list of fields to filter the final fields definitions.

Tags
example
$fields = $model->prepareQueryFields('full');
// Returns normalized array of fields including only those matching the 'full' skin
Return values
array<string, array<string|int, mixed>>|null

Normalized fields ready for query, or null if none.

prepareSearch()

Prepare the searchable AQL conditions — the classic `?search=` `LIKE` sweep, a parenthesized `OR` of case-insensitive `LIKE()` predicates over every (permitted) searchable field, used when no View search is active.

public prepareSearch([array<string|int, mixed>|string|null $search = [] ][, array<string|int, mixed>|null &$binds = null ][, array<string|int, mixed>|null $searchable = null ][, string $docRef = AQL::DOC ]) : string|null

The comma-separated terms and the fields are always OR-ed. How the words of a single term combine within a field follows the model's $searchOperator (Search::OPERATOR init key):

  • Logic::OR (default) matches the whole term as one substring (LIKE(doc.name, "%marc fourcade%")), so it needs the words adjacent and in order — the historical, byte-for-byte grammar;
  • Logic::AND splits the term on whitespace and requires every word in the same field (( LIKE(doc.name, "%marc%") && LIKE(doc.name, "%fourcade%") )), order-independent.
Parameters
$search : array<string|int, mixed>|string|null = []
$binds : array<string|int, mixed>|null = null
$searchable : array<string|int, mixed>|null = null
$docRef : string = AQL::DOC
Tags
throws
BindException
example
?search=Marc,Marco
Return values
string|null

prepareViewSearch()

Prepare the relevance-ranked `SEARCH` expression of an active View search, or `null` when the View search is inactive (no `AQL::VIEW` declaration, no searched fields, or no search term) — the caller then falls back to the classic `LIKE` sweep of {@see prepareSearch()}.

public prepareViewSearch([array<string|int, mixed>|string|null $search = [] ][, array<string|int, mixed>|null &$binds = null ][, string $docRef = AQL::DOC ]) : string|null

The grammar keeps the ?search= contract (comma-separated terms, OR everywhere, values bound — never inlined). Per term and per field:

  • the base match doc.<field> IN TOKENS(@search_N, "<analyzer>") (both sides analyzed), weighted by BOOST(…, <boost>) when the field boost differs from 1; a field reaching into an array of objects has its [*] expansion marker stripped here (doc.contactPoints.email IN …, not doc.contactPoints[*].email): the SEARCH grammar rejects array expansion, and the flat path already matches any element of the indexed array — see buildViewLink();
  • with a per-field or View-level Search::PHRASE, an exact-phrase bonus BOOST(PHRASE(doc.<field>, @search_N), <boost × 2>); a field may override the View-level flag (an explicit false opts that field out);
  • with a per-field or View-level Search::FUZZY > 0, a typo-tolerant LEVENSHTEIN_MATCH(doc.<field>, @search_N, <fuzzy>); a field may override the View-level tolerance — an explicit 0 opts that field out while the rest stays fuzzy.

Field expressions are grouped by their resolved Analyzer (a field may override the View-level Search::ANALYZER) and each group is wrapped in its own ANALYZER(…, "<analyzer>"), the groups being OR-ed together. With a single Analyzer the output is a single ANALYZER(…) wrap, byte for byte the classic form.

Search::REQUIRES gates the search by the request authorizer (Arango::AUTHORIZER, see isAuthorized()) at two levels: on the AQL::VIEW block it gates the whole search, inside a field entry it gates that field; the two combine with AND (fail-open without an authorizer). If the View-level gate is denied, or permissions remove every field, the expression is false — the search matches nothing and never falls back to searching everything.

When the request carries an active language (Arango::LANG, the ?lang= parameter), localized fields (those declaring Search::LANG) join the SEARCH only when their locale matches; locale-agnostic fields always do. An active language matching no field is ignored — the SEARCH is never emptied (within the permitted set).

Parameters
$search : array<string|int, mixed>|string|null = []

The $init array (reads Arango::SEARCH) or the search term itself.

$binds : array<string|int, mixed>|null = null

Bind variables, populated by reference.

$docRef : string = AQL::DOC

The document variable the fields hang off.

Tags
throws
BindException
ValidationException
Return values
string|null

The SEARCH expression, or null when the View search is inactive.

returnFields()

Generates an AQL document expression or LET statement with the selected fields.

public returnFields([array<string, mixed> $init = [] ][, array<string|int, mixed> &$variables = [] ][, bool $isVariable = false ]) : string

Supports edges, joins, skins, and query fields.

Parameters
$init : array<string, mixed> = []

viewDiff()

Compares the model's View declaration with the server state and reports the differences, without touching anything.

public viewDiff() : DiffReport

On top of the field/analyzer drift detected by ViewManagementTrait::viewDiff(), the model-level report validates the coherence of the declaration itself: a missing Search::NAME, no searched field, no collection, an analyzer or a collection unknown to the server all resolve to DiffStatus::INVALID — such a View is never created nor synchronized automatically.

Return values
DiffReport

viewSync()

Reconciles the model's View with its declaration: creates it when missing, repairs a drift with `updateProperties()` (the View stays available while the inverted index rebuilds in the background), and leaves {@see DiffStatus::IN_SYNC}, {@see DiffStatus::INVALID} or {@see DiffStatus::UNREACHABLE} reports untouched.

public viewSync() : DiffReport

throws
ValidationException
Return values
DiffReport

The viewDiff() report, with $applied set when the View has been created or updated.

Builds the View link of the model's collection from the `AQL::VIEW` declaration: every searched field (dotted paths become nested fields) is indexed with its resolved Analyzer — the per-field {@see Search::ANALYZER} when declared, otherwise the View-level one.

protected buildViewLink() : ArangoSearchLink

A field may reach a sub-field of an array of objects with the [*] expansion marker (e.g. contactPoints[*].email). The marker is stripped here (stripArrayExpansion()) so the link declares the flat nested path (contactPointsemail): ArangoSearch (Community) descends into the array on its own — no Enterprise nested flag is needed for this (non-correlated) search. The matching query strips the marker too — the SEARCH grammar rejects array expansion, see prepareViewSearch(). The stripped path is validated (assertAttributeName()) to reject a malformed declaration early.

A field whose resolved Analyzer equals the link-level default is emitted as an empty node (no analyzers key) rather than spelling the default out: the server normalizes a field whose analyzers equal the link default to } (the redundant mention is dropped), so spelling it out would make the declared form differ forever from the stored one and viewDiff() would report a permanent false drift. The link carries no link-level analyzers, so its default is the server default (identity) — computed here rather than hard-coded so the elimination stays correct if a link-level analyzer is introduced later.

ArangoSearchLink

buildViewSearchGroups()

Builds the per-Analyzer expression groups of the View search under the historical `OR` grammar : each comma-separated term is bound whole and matched in one shot per field (`doc.<field> IN TOKENS(@search_N, …)`, whose `IN` semantics already `OR` the term's tokens), plus the optional phrase and fuzzy branches. This is the exact grammar emitted when no field opts into {@see Search::OPERATOR} `AND` — see {@see prepareViewSearch()}.

protected buildViewSearchGroups(string $search, array<string|int, mixed>|null &$binds, string $docRef, array<string|int, mixed> $fields, string $modelAnalyzer, bool $globalPhrase, int $globalFuzzy) : array<string, array<string|int, string>>
Parameters
$search : string

The raw ?search= term string (comma-separated).

$binds : array<string|int, mixed>|null

Bind variables, populated by reference.

$docRef : string

The document variable the fields hang off.

$fields : array<string|int, mixed>

The resolved, gated per-field specs.

$modelAnalyzer : string

The View-level Analyzer (a per-field override is respected).

$globalPhrase : bool

The View-level phrase-bonus default.

$globalFuzzy : int

The View-level Levenshtein tolerance default.

Return values
array<string, array<string|int, string>>

buildViewSearchGroupsWithOperator()

Builds the per-Analyzer expression groups when at least one field opts into {@see Search::OPERATOR} `AND`. Each comma-separated term is split into words (whitespace) ; a field then combines those words with its resolved operator :

protected buildViewSearchGroupsWithOperator(string $search, array<string|int, mixed>|null &$binds, string $docRef, array<string|int, mixed> $fields, string $modelAnalyzer, bool $globalPhrase, int $globalFuzzy, string $globalOperator[, string|array<string|int, mixed>|null $separators = null ]) : array<string, array<string|int, string>>
  • OR (default) reproduces the whole-term match (pushWholeTermField()), so a mixed View keeps its loose fields loose ;
  • AND requires every word in the same field (( doc.<field> IN TOKENS(@w0, …) && doc.<field> IN TOKENS(@w1, …) )), the fuzzy branch (when enabled) widening each word (( … IN TOKENS(@w, …) || LEVENSHTEIN_MATCH(…, @w, …) )), and the phrase bonus (when enabled) kept on the whole term as a ranking boost OR-ed on top — an adjacency match implies the words, so the matched set is unchanged.

The whole-term bind is materialized only when a field needs it (an OR field, or an AND field carrying the phrase bonus), never left dangling. Groups are OR-ed between fields and between terms by prepareViewSearch().

Parameters
$search : string

The raw ?search= term string (comma-separated).

$binds : array<string|int, mixed>|null

Bind variables, populated by reference.

$docRef : string

The document variable the fields hang off.

$fields : array<string|int, mixed>

The resolved, gated per-field specs.

$modelAnalyzer : string

The View-level Analyzer (a per-field override is respected).

$globalPhrase : bool

The View-level phrase-bonus default.

$globalFuzzy : int

The View-level Levenshtein tolerance default.

$globalOperator : string

The View-level operator default (Logic::AND / Logic::OR).

$separators : string|array<string|int, mixed>|null = null

The extra AND word separators (Search::SEPARATORS); null = the hyphen default.

array<string, array<string|int, string>>

getSearchableSpecs()

Normalizes the model's `AQL::SEARCHABLE` list into a per-field specification map `field => [ (Search::REQUIRES => …)? ]`, the single source consumed by {@see prepareSearch()} (the `LIKE` sweep) and by the `searchable` fallback of {@see getViewFieldSpecs()}.

protected getSearchableSpecs([array<string|int, mixed>|null $searchable = null ]) : array<string, array<string, mixed>>

Each entry of the list is either:

  • a plain field name (string) → a public field, no options;
  • an array carrying the field name under Search::KEY plus its options (e.g. Search::REQUIRES) → keeps the list homogeneous (no mixed numeric/string keys). The map form field => [ … ] is also tolerated (the field falls back to the entry key).
Parameters
$searchable : array<string|int, mixed>|null = null

An explicit list overriding the model's searchable property.

Return values
array<string, array<string, mixed>>

getViewFieldSpecs()

Normalizes the searched fields of the `AQL::VIEW` declaration into a per-field specification map `field => [ Search::BOOST => float, … ]` — the single source of truth from which {@see getViewSearchFields()} derives the boost map and {@see prepareViewSearch()} resolves the per-field options.

protected getViewFieldSpecs() : array<string, array<string, mixed>>

Search::FIELDS entries accept a numeric boost shorthand or an array carrying Search::BOOST, Search::FUZZY, Search::ANALYZER, Search::LANG, Search::PHRASE and Search::REQUIRES; when the declaration has no fields, the model's searchable list is used with a neutral boost. A per-field option is kept in the spec only when it is explicitly declared — an absent key means "inherit the View-level default", which prepareViewSearch() resolves so that an explicit value (0 included) overrides the global tolerance.

ValidationException
Return values
array<string, array<string, mixed>>

getViewSearchFields()

Normalizes the searched fields into a `field => boost` map — a boost-only façade over {@see getViewFieldSpecs()}, used by {@see buildViewLink()} and {@see viewDiff()} which only care about the field paths and their weights.

protected getViewSearchFields() : array<string, float>

Return values
array<string, float>

ngramMatch()

Builds the `NGRAM_MATCH(doc.<field>, @term [, threshold], "<analyzer>")` core of a {@see Search::NGRAM} branch (without the surrounding boost). The threshold is inlined only when the field declares one, else the server default applies. Shared by the whole-term and the per-word emissions.

protected ngramMatch(array<string|int, mixed> $spec, string $path, string $term) : string
Parameters
$spec : array<string|int, mixed>

The field spec (must carry a Search::NGRAM entry).

$path : string

The doc.<field> accessor.

$term : string

The bound term (@search_N or @search_N_M).

Return values
string

The NGRAM_MATCH(…) expression.

pushWholeTermField()

Pushes the whole-term match of one field onto the Analyzer groups — the base `doc.<field> IN TOKENS(@term, …)` (boosted when the field weight is not `1`), the optional exact-phrase bonus and the optional fuzzy branch, plus the {@see Search::NGRAM} branch when declared. This is the `OR`-grammar emission, shared by {@see buildViewSearchGroups()} (every field) and by the `OR` fields of {@see buildViewSearchGroupsWithOperator()}.

protected pushWholeTermField(array<string|int, mixed> &$groups, array<string|int, mixed> $spec, string $path, string $term, array<string|int, mixed> $analyzers, float $weight, bool $phrase, int $fuzzy) : void
Parameters
$groups : array<string|int, mixed>

Analyzer name => list of expressions, mutated by reference.

$spec : array<string|int, mixed>

The resolved field spec.

$path : string

The doc.<field> accessor.

$term : string

The bound whole term (@search_N).

$analyzers : array<string|int, mixed>

The Analyzers indexing the field (IN TOKENS side).

$weight : float

The field boost.

$phrase : bool

Whether to add the exact-phrase bonus.

$fuzzy : int

The Levenshtein tolerance (0 disables the branch).

resolveFieldSearchSpec()

Resolves the per-field search facets shared by both group builders : the Analyzers indexing the field (a per-field {@see Search::ANALYZER} overrides the View-level one, a single Analyzer normalized to a one-element list), the boost, the fuzzy tolerance and phrase bonus (a per-field value overrides the View-level default), and the `doc.<field>` accessor (with the `[*]` array marker stripped — the flat path already matches any element of the indexed array, and the `SEARCH` grammar rejects the expansion form).

protected resolveFieldSearchSpec(array<string|int, mixed> $spec, int|string $field, string $modelAnalyzer, bool $globalPhrase, int $globalFuzzy, string $docRef) : array{0: string[], 1: float, 2: int, 3: bool, 4: string}
Parameters
$spec : array<string|int, mixed>

The resolved field spec.

$field : int|string

The field key (the dotted path, [*] allowed).

$modelAnalyzer : string

The View-level Analyzer.

$globalPhrase : bool

The View-level phrase-bonus default.

$globalFuzzy : int

The View-level Levenshtein tolerance default.

$docRef : string

The document variable the field hangs off.

Return values
array{0: string[], 1: float, 2: int, 3: bool, 4: string}

[ analyzers, weight, fuzzy, phrase, path ].

splitSearchTermWords()

Splits an `AND`-operator search term into its words, on whitespace plus the given extra separator characters ({@see Search::SEPARATORS}). Whitespace always splits; `$separators` adds literal characters (a string, or a list of characters joined to one), `null` falls back to the hyphen default, and an empty value splits on whitespace only. The extra characters are regex-escaped, so any punctuation is safe. Empty words are dropped.

protected splitSearchTermWords(string $term[, string|array<string|int, mixed>|null $separators = null ]) : array<string|int, string>
Parameters
$term : string

The raw comma-term (may hold several words).

$separators : string|array<string|int, mixed>|null = null

The extra separator characters (string / list / null=default hyphen).

Return values
array<string|int, string>

The non-empty words, in order.

filterFieldsBySkin()

Filters fields based on an optional skin.

private filterFieldsBySkin(array<string, mixed> $fields, string|null $skin) : array<string, mixed>
Parameters
$fields : array<string, mixed>

Fields to filter

$skin : string|null

Skin to match

Return values
array<string, mixed>

Filtered fields

generateUniqueKey()

Generates a unique key for special filters like edges, joins, or unique names.

private generateUniqueKey(string $key, string|null $filter[, string|null $parentKey = null ]) : string|null
Parameters
$key : string

Base field key

$filter : string|null

Filter type

$parentKey : string|null = null

Optional parent key.

Return values
string|null

Generated unique key or existing

normalizeFieldDefinition()

Normalize a field definition into a structured array for queries.

private normalizeFieldDefinition(string $key[, array<string|int, mixed> $options = [] ][, string|null $parentKey = null ][, string|null $skin = null ]) : array<string, mixed>|null
  • Converts string filters to array
  • Handles subfields for DOCUMENT or MAP filters
  • Generates unique keys for special filters

The sub-fields of a structural filter (WRAP, DOCUMENT, MAP) are prepared recursively with the SAME skin, so a Field::SKINS marker on a nested sub-field is honored at every depth — with the level-one rules: a sub-field without a marker is always kept, and a null skin keeps everything. When the skin filters out ALL the declared sub-fields, the method returns null and the field itself is dropped from the projection (key absent).

A structural field can also declare per-skin alternative sub-projections through AQL::SKIN_FIELDS (same table shape and resolution order as an edge/join definition). A declared table that resolves to nothing for the requested skin drops the field the same way (returns null).

Parameters
$key : string

Field name

$options : array<string|int, mixed> = []

Field options, may include:

  • Field::FILTER
  • Field::NAME
  • Field::QUOTED
  • Field::FIELDS (for DOCUMENT or MAP)
$parentKey : string|null = null

The Optional parent key

$skin : string|null = null

Optional skin propagated to the nested sub-fields.

Tags
example
$normalized = $this->normalizeFieldDefinition( 'permissions',
[
    Field::FILTER => Filter::EDGES,
    Field::SKINS => [Skin::FULL]
]);
Return values
array<string, mixed>|null

Normalized field definition, or null when the skin removed every declared sub-field.
