    Description

      Because of the optimization introduced in LUCENE-9449, 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.
