Hi @BenTrent, thanks a lot for your solution. It is simple yet effective!

Another thing I noticed in the documentation that is currently holding us back, is the limitation to retrieve only the best match vector regardless of the "size" parameter in the inner\_hits.

I made a [separate post](https://discuss.elastic.co/t/size-parameter-ignored-in-nested-knn-search/350285) about that in order to not clutter this page.
