Properties

BuildSliceMs: number

Milliseconds of index building per event-loop turn while an index is built in the background. Default 8.

Connectivity: number

HNSW graph connectivity (edges per node). Default 16.

Enabled: boolean

Build HNSW indexes for large cosine stores. Default false.

ExpansionSearch: number

Candidate list size during search; higher trades speed for recall. Default 64.

MinRows: number

Live rows a store needs before an HNSW index is built for it. Default 50,000.

Oversample: number

Candidates fetched per requested result, before exact re-ranking and filtering. Default 4.
