[GitHub] [lucene-solr] mayya-sharipova opened a new pull request #2530: LUCENE-10020 DocComparator don't skip docs of same docID
mayya-sharipova opened a new pull request #2530:
URL: https://github.com/apache/lucene-solr/pull/2530
DocComparator should not skip docs with the same docID on multiple
sorts with search after.
Because of the optimization introduced in LUCENE-9449, currently when
searching with sort on [_doc, other fields] with search after,
DocComparator can efficiently skip all docs before and including
the provided [search after docID]. This is a desirable behaviour
in a single index search. But in a distributed search, where multiple
indices have docs with the same docID, and when searching on
[_doc, other fields], the sort optimization should NOT skip
documents with the same docIDs.
This PR fixes this.
