When you try to percolate a knn query, it currently is not supported: "the [knn] query is unsupported inside a percolator query"
It would be great to have this functionality. I do understand a vector query matches every document, but in combination with a min\_score restriction, this would be great.

This is an interesting idea @edwineve , may we know a little bit more around the use-case?
I could see how using min\_score, or a required `similarity` COULD work.

@BenTrent: We are trying to do news-monitoring using vector-embeddings. We determine the min\_score based on the current newsarchive results, and would like to use the percolator (as we do for our boolean queries), to do newsalerting.
