Plug: If you're ever looking for an open source alternative to Pinecone, we recently added vector search to Typesense: https://typesense.org/docs/0.24.1/api/vector-search.html

The key thing is that it's in-memory and allows you to combine attribute-based filtering, together with nearest-neighbor search.

We're also working on a way to automatically generate embeddings from within Typesense using any ML models of your choice.

So Algolia + Pinecone + Open Source + Self-Hostable with a cloud hosted option = Typesense

This is what we’re using. We already sync database content to a typesense DB for regular search so it wasn’t much more work to add in embeddings and now we can do semantic search.

Could you do boosting with Typesense, like favoring more recent results?

[jabo]

Yup. If you store timestamps as Unix timestamps you can gave Typesense sort on text match score and the timestamp field: https://typesense.org/docs/guide/ranking-and-relevance.html#...
