Type Alias: VectorStoreMetric

VectorStoreMetric = "cosine" | "dot"

Defined in: extensions/vectorStore.ts:16

How a VectorStore scores a stored vector against a query.

• 'cosine': cosine similarity, in [-1, 1]. Neither side has to be normalized. A zero vector scores 0 against everything.
• 'dot': the raw dot product. Equal to cosine for L2-normalized vectors (which every embedder in the models registry emits) and slightly cheaper.
