Hi, I’m looking to implement a hybrid search combining kNN and BM25. Is it possible to use retrievers in the open-source version of Elasticsearch to perform this in a single search query instead of using multi-search?

Using retrievers in the open source version

I think we can continue the discussion in the other thread as it's related.
