### Description Summary of mailing list thread... https://lists.apache.org/list.html?java-u...@lucene.apache.org * Using `UnifiedHighlighter` w/ `DefaultPassageFormatter` * Highlighting fields that use `setStoreTermVectors(true)` + `setStoreTermVectorOffsets(true)` * but do *NOT* use `setStoreTermVectorPositions(true)` * `IndexOutOfBoundsException` can occur in `DefaultPassageFormatter` -> `StringBuilder` when query and field includes multiple terms * Problem caused by `TermVectorOffsetStrategy` producing `Passage` instances where matches are not in order (by start offset) * Not clear from `Passage` API if this is allowed * `DefaultPassageFormatter` does not expect this (only the possibility that end/start will overlap) * Problem started happening "by default" in 9.0 due to LUCENE-9431 * #362 * Known workarounds: * Index Time Option: Add `setStoreTermVectorPositions(true)` to fields you wish to highlight that already use `setStoreTermVectors(true)` * Alternative Query Time Option: Subclass `UnifiedHighlighter` to override `getFlags(String)` and remove `HighlightFlag.WEIGHT_MATCHES` from the set returned by `super.getFlags(field)` Test patch demonstrating problem in above linked mailing list thread ### Version and environment details _No response_ -- This is an automated message from the Apache Git Service.
