Facets only on hits actually returned

Elastic Stack Elasticsearch
1

This may sound like a strange question but is there a way to get facets
only for the hits actually returned? So for example, if there are 100k
total hits but I only asked for 100 in the size parameter, I only want the
facets on the 100 actually returned. Obviously I could just go through the
100 results and do the aggregation myself but wanted to see if there was a
way to let elasticsearch/lucene do it. I know there is facet scopes and
facet filters but I just need the facets on the actual returned hits.
much thanks

I think that if you add a limit filter in your FilteredQuery it should work.
But only for the 1st page.

There is an open issue for this request, but no comment from the
elasticsearch team in two years:

I have a vague how to implement such as feature with the old facets, but
not with the new aggregation framework. No clue if it would make the task
easier or not. Perhaps I should look into it.
