> Key: LUCENE-9599
> URL: https://issues.apache.org/jira/browse/LUCENE-9599
> Project: Lucene - Core
> Issue Type: Improvement
> Reporter: Mayya Sharipova
> Priority: Minor
> Fix For: 8.8

> Time Spent: 3h 50m
> Remaining Estimate: 0h

> LUCENE-9280 introduced an ability for comparators to skip non-competitive documents. But currently comparators are not aware of index sorting, and can run sort optimization even when search sort is congruent with the index sort.
> As the early termination in this case is already handled in TopFieldCollector, we need to disable sort optimization in comparators.
