Hello everyone!
I’m really interested by the new kNN search functionality of Elasticsearch v8.
Is there any way to run an approximate kNN search on multiple dense\_vectors?
I checked the docs but, as of version 8.1.0, there’s no mention about it. Moreover, I tried to create a multi-vector query and execute it through Kibana dev tools console but it doesn’t seem to be supported.
Thank you so much,
Riccardo

What do you mean by `run an approximate kNN search on multiple dense_vectors`?
If you mean that can a single field have multiple vectors, it is currently not supported.
Also providing multiple query vectors is not supported. But what you can do instead is to issue multiple `_knn_search` requests with each own `query_vector` and combine results on your application side.

You can follow [this development](https://www.elastic.co/guide/en/elasticsearch/reference/master/knn-search.html#_search_multiple_knn_fields), which was not (yet) released. I think it may provide you the capability you are seeking. It is related to issue [#91187](https://github.com/elastic/elasticsearch/issues/91187) and PR [#92118](https://github.com/elastic/elasticsearch/pull/92118) and as you can see it is merged for v8.7 (note, this is not a commitment that it will be released then or at all, but we work transparently and you can draw your own conclusions).
