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](https://world.optimizely.com/support/Bug-list/bug/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](https://world.optimizely.com/support/Bug-list/bug/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](https://world.optimizely.com/support/Bug-list/bug/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](https://world.optimizely.com/support/Bug-list/bug/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. ## July 22, 2025 ***EPiServer.Find 16.6.0*** **Enhancement** - Enhancements were made to support language routing for msearch requests in the .NET Client. **Bug fixes** - [FIND-13994](https://world.optimizely.com/support/Bug-list/bug/FIND-13994) – Fixed an issue where indexing Excel files with a high number of columns, a memory leak can occur, which can prevent the indexing job from completing. - [FIND-14004](https://world.optimizely.com/support/Bug-list/bug/FIND-14004) – Fixed the issue where it shouldn't clear all local languages at the beginning of the indexing job; clean up local languages after the job finishes instead. ## April 8, 2025 ***EPiServer.Find 16.5.0*** **Bug fix** - [FIND-13832](https://world.optimizely.com/support/Bug-list/bug/FIND-13832) – Removed the `GetAwaiter()` method in async calls. ## March 18, 2025 ***EPiServer.Find 13.6.1*** **Bug fix** - [FIND-13135](https://world.optimizely.com/support/Bug-list/bug/FIND-13135) – Fixed an issue where the best bet `constant_score` query failed to guarantee the best bets to get the highest score. ## March 11, 2025 ***EPiServer.Find.CMS 16.4.1*** **Bug fixes** - [FIND-13649](https://world.optimizely.com/support/Bug-list/bug/FIND-13649) – Fixed an issue where the statistics cache had to be cleared more frequently than needed. - [FIND-13671](https://world.optimizely.com/support/Bug-list/bug/FIND-13671) – Fixed an issue where the query generation was incorrect for the fallback language. - [FIND-12914](https://world.optimizely.com/support/Bug-list/bug/FIND-12914) – Fixed an issue that significantly improved performance and fixed inconsistencies in cache key generation for certain culture codes. - [FIND-13512](https://world.optimizely.com/support/Bug-list/bug/FIND-13512) – Fixed an issue where the CMS site cannot start because of Search and Navigation endpoint failure. - [FIND-13551](https://world.optimizely.com/support/Bug-list/bug/FIND-13551) – Fixed an issue where sending a request to `/find_v2/` on a configured application returns an `HTTP 500 error`. - [FIND-13663](https://world.optimizely.com/support/Bug-list/bug/FIND-13663) – Fixed an issue where an indexing job runs for an extended period. - [FIND-13678](https://world.optimizely.com/support/Bug-list/bug/FIND-13678) – Fixed a null reference exception error when migrating from `EPiserver.Find.Cms` from 16.2.0 to 16.4.0. ## January 14, 2025 ***EPiServer.Find.CMS 16.4.0*** **Enhancement** - Added a slider and a decimal input field on the Boosting dashboard for specific and precise tuning adjustments. **Bug fixes** - [FIND-13291](https://world.optimizely.com/support/Bug-list/bug/FIND-13291) – Fixed an issue that would delete content of other sites when `ReindexMySitesOnly` was enabled.
