--------------------------------------
What collector do you have in mind? Is it TopFieldCollector?
> Early Terminating CollectorManager
> ----------------------------------
>
> Key: LUCENE-8929
> URL: https://issues.apache.org/jira/browse/LUCENE-8929
> Project: Lucene - Core
> Issue Type: Improvement
> Reporter: Atri Sharma
> Priority: Major
>
> We should have an early terminating collector manager which accurately tracks
> hits across all of its collectors and determines when there are enough hits,
> allowing all the collectors to abort.
> The options for the same are:
> 1) Shared total count : Global "scoreboard" where all collectors update their
> current hit count. At the end of each document's collection, collector checks
> if N > threshold, and aborts if true
> 2) State Reporting Collectors: Collectors report their total number of counts
> collected periodically using a callback mechanism, and get a proceed or abort
> decision.
> 1) has the overhead of synchronization in the hot path, 2) can collect
> unnecessary hits before aborting.
> I am planning to work on 2), unless objections
