[LUCENE-10674] BitSetConjunctionDISI iterators fall out of sync when lead doc >= minlength of bitsets

• Type: Bug

Description

In BitSetConjunctionDISI.doNext() 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(), 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.
