Well Weaviate is graphql and it has filtering and hybrid search which is a great feature that pg can’t fully support because it doesn’t have bm25

I have a ChatGPT session where I have asked it to do a hybrid search using filtering, pg fts and vector search. Looks reasonable just need to test it and write it up somewhere.
