Show HN: DuckDB community extension for prefiltered HNSW using ACORN-1

Hey folks!

As someone doing hybrid search daily and wishing I could have a pgvector-like experience but with actual prefiltered approximate nearest neighbours, I decided to just take a punt on implementing ACORN on a fork of the DuckDB VSS extension.

I had to make some changes to (vendored) usearch that I’m thinking of submitting upstream.

But this does the business.

Approximate nearest neighbours with WHERE prefiltering.

Edit: Just to clarify, this has been accepted into the community extensions repo.

So you can use it like: INSTALL hnsw_acorn FROM community; LOAD hnsw_acorn; Comments URL: https://news.ycombinator.com/item?id=47512891 Points: 29 # Comments: 1
