Adrien Grand commented on LUCENE-8791:
--------------------------------------

bq. Sometimes this set is not that small, Documents may be enriched during 
indexing time, hence too many may match.

We don't do anything to prevent from using rescorers on lots of hits, but I'd 
rather not optimize for this use-case. In my opinion, rescorers should be used 
on the very top hits only.
