QueryText and QueryEmbedding options are empty

[pyphp]

This embedded vector database is really great and very suitable for Go language development. When I try to query content only through metadata and filtering without performing similarity search, I get an error: 'QueryText and QueryEmbedding options are empty'. Can this scenario be supported?

Hey 👋 , Sorry for the late reply!

Regarding the proposed scenario, it's an interesting idea, I didn't think the library would be used without the similarity search. I think it can be interesting to support it, but would probably add a separate method for this. The Query and QueryWithOptions methods currently say "Query performs an exhaustive nearest neighbor search on the collection." and "QueryWithOptions performs an exhaustive nearest neighbor search on the collection." respectively, so really focused on the similarity search.

Would you be interested in contributing a new Collection.Filter method for this? The implementation could probably just call existing lower level functions, like here.
