Recommended action: Use halfvec (column or expression index: embedding::halfvec(N) with halfvec_*_ops) for up to 4,000 dims, binary quantization for more, index subvectors, or request a smaller embedding size (models supporting a dimensions parameter).
Option: Index a halfvec expression [evidence: official_recommended_action]
Applies when: 2001-4000 dim embeddings
Steps:
1. CREATE INDEX ON items USING hnsw ((embedding::halfvec(3072)) halfvec_cosine_ops);
2. Query with ORDER BY embedding::halfvec(3072) <=> $1::halfvec(3072)
Expected: HNSW index builds and is used
Evidence basis (self-declared by the contributing chat client): untested.
