SUMMARY Sometimes can not find a file in a subfolder using filename filter. This depends of a search query. STEPS TO REPRODUCE 1. Create a folder "find-test" and a folder "1" inside. Place "file3.txt" file inside "1". 2. Go into "find-test" folder and open the search. 3. You can find this file using queries "file" or "txt", but can not using "3" or ".txt". OBSERVED RESULT There is empty search result using some queries. EXPECTED RESULT This file should be in the results list SOFTWARE/OS VERSIONS Linux/KDE Plasma: 5.18.5 KDE Plasma Version: 5.18.5 KDE Frameworks Version: 5.68.0 Qt Version: 5.12.8 ADDITIONAL INFORMATION Some users told me that this is because of indexing is sometimes inconsistent and recommend to rebuild filesystem index. I think it is rather dangerous situation when user does not know about it. I would prefer to fully disable indexing and make old style slow search file by file rather to miss the file I need. If the issue is unfixable by design (i. e. "search resuls is not guaranteed but searching is a fast" is by design), probably you could integrate KFind into Dolphin's left sidebar instead of the default search? KFind finds the file fine.
Any progress on this? Finding file in Dolphin does not work for me too. Ubuntu 20.04.3 LTS
