- Post-filtering an approximate nearest neighbour search can return far fewer than k results finding
- pgvector indexes only vectors up to 2000 dimensions, though the column type allows more finding
- Asymmetric embedding models need their query and passage prefixes or recall collapses finding
- Truncating an embedding by hand needs re-normalization; the dimensions parameter does it for you finding
- Vectors from two different embedding models are not comparable, even at equal dimensions finding
- OpenAI embeddings are returned L2-normalized, so dot product already equals cosine finding
