Types ¶
type Store ¶
type Store struct {
// contains filtered or unexported fields
}
Store is an in-memory vector store with brute-force cosine similarity search.
func (*Store) DeleteByMetadata ¶
DeleteByMetadata removes entries matching the given metadata filter. An empty filter would match every entry and is ErrInvalidArgument.
func (*Store) Describe ¶
func (*Store) Describe() weave.ComponentInfo
Describe reports the in-memory vector store: cosine similarity, and an exact tenant_id metadata filter that is covered by Weave's own tests.
func (*Store) Search ¶
func (s *Store) Search(_ context.Context, vector []float32, opts *vectorstore.SearchOptions) ([]vectorstore.SearchResult, error)
Search returns the most similar entries of one tenant to the given vector using cosine similarity. An empty TenantKey is ErrTenantRequired.
