🤖 *AI text below* 🤖 *(posted on behalf of Nick Shanin)* https://issues.apache.org/jira/browse/SOLR-16130 Regression test for the SOLR-16130 symptom: a cross-collection join returning no documents when the from-collection's export has a trailing segment with no matches. The root-cause fix (a null-bitset guard in `ExportWriter.topDocs()`) already merged in #4953 (SOLR-8291); this PR adds the test proving the reported scenario now works, plus the changelog entry. - `CrossCollectionJoinQueryTest.testCcJoinWithTrailingUnmatchedExportSegment`: indexes matching docs, commits, indexes non-matching docs, commits (trailing unmatched segment), then runs the cross-collection join and expects the 4 matching docs. - Enables `useFilterForSortedQuery` in the ccjoin test configset: that setting routes `/export` through `sortDocSet`, which is the path that skips `getLeafCollector` for trailing unmatched leaves (per #4953's analysis). Only `CrossCollectionJoinQueryTest` uses this configset. Tests: `CrossCollectionJoinQueryTest` validation still to run. ### AI assistance AI agents assisted with research, implementation, review, and drafting.
