Jack Mazanec updated LUCENE-10674:
----------------------------------
Description:
In
[BitSetConjunctionDISI.doNext()|https://github.com/apache/lucene/blob/releases/lucene/9.3.0/lucene/core/src/java/org/apache/lucene/search/ConjunctionDISI.java#L283-L285]
if the lead doc is greater than or equal to the length of any of the BitSets,
NO_MORE_DOCS is returned.
On subsequent calls to
[BitSetConjunctionDISI.docId()]([https://github.com/apache/lucene/blob/releases/lucene/9.3.0/lucene/core/src/java/org/apache/lucene/search/ConjunctionDISI.java#L263]),
the lead's docID which is not exhausted will be returned.
I think this could be fixed by calling lead.advance(NO_MORE_DOCS) before
returning NO_MORE_DOCS in doNext.
