December 17, 2025
EPiServer.Find 16.7.0
Enhancements
- Added improvements to cache key generation for search requests, enhancing system performance. This includes optimizing the method for creating cache keys and reducing redundant calls to the GetCacheKey function, ensuring it is invoked only once per search request.
- Added logic to automatically ensure the ServiceUrl includes a trailing slash when read from the configuration file. This change improves resource efficiency by performing the check and addition once, and optimizes the internal method for verifying the trailing slash.
- Added the capability to manage statistical-related queries under the Related Queries tab in the Search & Navigation Optimization UI. You can now delete statistical-related queries from the database or edit them. Editing a statistical-related query converts it into an editor-related query. This provides greater flexibility to refine your Did you Mean suggestions.
Bug fixes
- FIND-13379 – Fixed an issue where the Import/Export functionality on the .NET client failed to automatically detect UTF-8 encoding in CSV files, requiring you to manually decode them. The system now automatically detects and decodes UTF-8 CSV files for seamless import.
- FIND-14026 – Fixed an issue where bestbets items in the local language would display the wrong URL segment (fallback language instead of local language) after a refresh, also affecting the search UI. Bestbet items are now correctly retrieved in the original language first, ensuring accurate URL segments.
- FIND-14365 – Fixed an issue where ProjectionHelper could throw casting exceptions due to incorrect numeric type casting; now uses a value converter to ensure proper type handling and prevent these exceptions.
- FIND-14434 – Fixed an issue where Search(Language.All) and UnifiedSearch(Language.All) methods caused a CultureNotFoundException due to a missing Language.All handler. This binary-breaking change is now resolved, ensuring search operations function correctly.
