[jira] [Commented] (LUCENE-9280) Add ability to skip

Commit 99220677fe409bab5c4206dc31f186d0c4335280 in lucene-solr's branch refs/heads/master from Mayya Sharipova

LUCENE-9449 Skip docs with _doc sort and "after" (#1725)
- Enhance DocComparator to provide an iterator over competitive
documents when searching with "after". This iterator can quickly position
on the desired "after" document skipping all documents and segments before
"after".
- Redesign numeric comparators to provide skipping functionality
by default.

> Today collectors, once they collect enough docs, can instruct scorers to update their iterators to skip non-competitive documents. This is applicable only for a case when we need top docs by _score.
> It would be nice to also have an ability to skip non-competitive docs when we need top docs sorted by other fields different from _score.
