IndexType uses ConstantsTrait

Type values accepted by the ArangoDB index API as the `type` field of a `POST /_api/index` request (and returned on the response side).

Notes:

primary and edge are server-managed and cannot be created through POST /_api/index — they are listed here for completeness (the Collection::indexes() listing exposes them as-is).
hash and skiplist are aliases of persistent since ArangoDB 3.7 and are intentionally NOT exposed — use PERSISTENT.
fulltext has been deprecated since ArangoDB 3.10 in favour of INVERTED / ArangoSearch views.

EDGE : string = 'edge': Built-in edge index automatically created on every edge collection.
FULLTEXT : string = 'fulltext': Full-text inverted index. Deprecated since ArangoDB 3.10 in favour of {@see INVERTED} / ArangoSearch views.
GEO : string = 'geo': Geospatial index (point or polygon-aware).
INVERTED : string = 'inverted': Inverted index (ArangoSearch-backed). Replacement for `fulltext`.
MDI : string = 'mdi': Multi-dimensional index (stable since ArangoDB 3.12).
MDI_PREFIXED : string = 'mdi-prefixed': Multi-dimensional index with explicit prefix fields (ArangoDB 3.12+).
PERSISTENT : string = 'persistent': Persistent (B-tree) index — the default for most use cases.
PRIMARY : string = 'primary': Built-in primary index automatically created on every collection (`_key` lookup). Cannot be created manually; listed for completeness.
TTL : string = 'ttl': Time-to-live index that removes documents past their `expireAfter` threshold.
VECTOR : string = 'vector': Vector index (ArangoDB 3.13+, Faiss-backed). Used for similarity search over embedding vectors.

Built-in edge index automatically created on every edge collection.


    public
        string
    EDGE
    = 'edge'

Cannot be created manually; listed for completeness.

Full-text inverted index. Deprecated since ArangoDB 3.10 in favour of {@see INVERTED} / ArangoSearch views.

        string
    FULLTEXT
    = 'fulltext'

Geospatial index (point or polygon-aware).


    public
        string
