I can't speak to the others, but pgvector indices can "break" hybrid queries. For example, if you select using a where clause specifying metadata (where genre = jazz) and order by distance from a vector (embedding of sound clip); if the index doesn't have a lot (or any) vectors in the sphere of the query vector that also match the metadata it can return no results. I discuss this in a blog post here [1]. [1]: https://www.polyscale.ai/blog/pgvector-bigger-boat/ |
