Performance would depend on how many candidate docs were in range of Doc X. It wouldn't scale well for lots of candidates, that's for sure.

I think this is similar to a [question I also failed to answer](https://discuss.elastic.co/t/how-to-get-only-n-documents-for-each-value/49795/6?u=loren) a while back, which also seemed like a computational geometry problem that could not be solved with a single ES query. Sorry I could not be more helpful!
