Atri Sharma commented on LUCENE-8929:
-------------------------------------
Ok, so I have been working on this and am wondering what the definition
(parameter) of a globally competitive hit be. Should it be the largest of the
worst accepted hit across all collectors, and all collectors use that as the
minimum threshold when filtering further hits?

> Project: Lucene - Core
> Issue Type: Improvement
> Reporter: Atri Sharma
> Priority: Major
> Time Spent: 40m
> Remaining Estimate: 0h
>
> 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
