Constants

SEARCHABLE : string = 'searchable': The 'searchable' parameter key.

Properties

$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()}).
$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.
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.
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}.
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).
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()}.
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.

SEARCHABLE

The 'searchable' parameter key.


    public
        string
    SEARCHABLE
    = 'searchable'

$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.

$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.

bind()

Bind a value to an AQL query variable.


    public
                    bind(mixed $value[, array<string|int, mixed> &$binds = [] ][, string|null $to = null ]) : string

Parameters

$value : mixed: The value to bind to the query.
$binds : array<string|int, mixed> = []: Reference to the array of existing bind variables.
$to : string|null = null: Optional name of the bind variable. If null, a unique name is generated.

Return values

string —

The formatted bind variable (including the "@" prefix as needed) for use in the query.

bindCollection()

Bind a collection name to an AQL query variable.


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

Prepares a bind variable for a collection name. Uses the collection defined in $init or falls back to $this->collection if none is provided.

Parameters

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

Reference to the array of existing bind variables. If null, a new array is used.

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

Optional initialization array with keys:

Arango::COLLECTION => the collection name to bind
Arango::NAME => optional bind variable name

Return values

string —

The formatted bind variable representing the collection.

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.

Return values

string —

The formatted bind variable representing the View.

getViewLinks()

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.


    public
                    getViewLinks() : array<string, ArangoSearchLink>

Return values

array<string, ArangoSearchLink>

getViewName()

Returns the name of the declared View ({@see Search::NAME} of the `AQL::VIEW` block), or `null` when the model declares none.


    public
                    getViewName() : string|null

Return values

string|null

hasViewSearch()

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.


    public
                    hasViewSearch([array<string|int, mixed>|string|null $search = [] ]) : bool

Parameters

$search : array<string|int, mixed>|string|null = []: The $init array (reads Arango::SEARCH) or the search term itself.

Return values

bool

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).


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

Parameters

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

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

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> = []

Return values

static

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

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.

Return values

string|null —

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

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

Return values

DiffReport —

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

buildViewLink()

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 (contactPoints → email): 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.

Return values

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>> —

Analyzer name => list of expressions, in first-seen order.

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.

Return values

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

Analyzer name => list of expressions, in first-seen order.

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.

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.
