Environmental Setup: We've configured full crawl weekly once and incremental crawl 3 times daily. We have a library, which has > 3000 files.
Issue: Whenever a user search(Library Search) for a particular name(for example: full name), search results are showing older records which crawled last time and not displaying the latest search results. When the user searches with a particular name(for example: last name), search results are showing the latest results.
Scenario: 1. When user searches "Ólafur Viktor" - it gives latest results 2. When user searches "Ólafur" - it gives older results 3. When user searches "Viktor" - it gives latest results
When I re-index this library, search works fine but after some days the issue again comes up and the same above scenario persists.
Please let me know how to fix this error related to Search indexing. Thanks
