The subtype of the AI Search index, determining the indexing and retrieval strategy.
VECTOR: Not a supported create value — do not select it. Use HYBRID (vector + hybrid
search) or FULL_TEXT (full-text only). It is the proto2 default (= 0) solely to mirror
the legacy index_v2.proto enum value-for-value; it is not an offered index subtype.
FULL_TEXT: An index that uses full-text search without vector embeddings.
HYBRID: An index that uses vector embeddings for similarity search and hybrid search.
