Adrien Grand commented on LUCENE-8788:
--------------------------------------
I think this is definitely worth exploring. It looks like a subset ofÂ
LUCENE-8727, since we are only aiming at using fully collected slices here to
speed up slices that have not been collected yet.

> Project: Lucene - Core
> Issue Type: Improvement
> Reporter: Atri Sharma
> Priority: Major
>
> We offer no guarantee on the order in which an IndexSearcher will look at
> segments during a search operation. This can be improved for use cases where
> an engine using Lucene invokes early termination and uses the partially
> collected hits. A better model would be if we sorted segments by the
> estimated number of hits, thus increasing the probability of the overall
> relevance of the returned partial results.
