See [result diversity](/en/result-diversity.html) for strategies on how to create result sets from different sources.

#### How to find most distant neighbor in a embedding field called clip_query_embedding?
If you want to search for the most dissimilar items,
you can with angular distance multiply your `clip_query_embedding` by the scalar -1.
Then you are searching for the points that are closest to the point
which is the farthest away from your `clip_query_embedding`.
