 # Changelog
 
+## 2025-04-22 - 5.12.2 - fix(search)
+Fix handling of quoted wildcard patterns in field-specific search queries and add tests for location-based wildcard phrase searches
+
+- Strip surrounding quotes from wildcard patterns in field queries to correctly transform them to regex
+- Introduce new tests in test/test.search.ts to validate exact quoted and unquoted wildcard searches on a location field
+
 ## 2025-04-22 - 5.12.1 - fix(search)
 Improve implicit AND logic for mixed free term and field queries in search and enhance wildcard field handling.
