We're fighting with an issue after upgrading our SharePoint 2013 Farm to April 2017 CU (15.0.4919.1003).
The in-place search seems not to filter at all. Instead all list items are shown - regardless of the search-term.
The list of things we've tried so far:
- Executed the SharePoint Config Wizzard (without error)
- Started a full crawl
- Ensured that all relevant managed properties are marked as searchable
- Restarted any kind of services or machine that could (or could not) be related
- Checking the event log and ULS logs (the're looking good to me)
Any solution we have found so far were targeting issues where the in-place search returns an empty search result.
The previous version was 15.0.4797.1000.
Is there any known issue with this update that could explain this behaviour?
