 ### Changed
+- unsignedLongRangeQuery now returns MatchNoDocsQuery if the lower bounds are greater than the upper bounds ([#14416](https://github.com/opensearch-project/OpenSearch/pull/14416))
 - Make the class CommunityIdProcessor final ([#14448](https://github.com/opensearch-project/OpenSearch/pull/14448))
 - Updated the `indices.query.bool.max_clause_count` setting from being static to dynamically updateable ([#13568](https://github.com/opensearch-project/OpenSearch/pull/13568))
