SUMMARY If you turn off Baloo File Indexing overall, but keep Baloo enabled, and then search for files in Dolphin it'll immediately finish with 0 results, irregardless of if there's actual files to find that match your query. STEPS TO REPRODUCE 1. Turn off indexing file content and folder-specific indexing in File Search KCM 2. Keep Baloo itself enabled 3. Apply, and perform a search in Dolphin OBSERVED RESULT Search immediately finishes with 0 results EXPECTED RESULT Search would continue using the filename search service if not Baloo searching by filenames. SOFTWARE/OS VERSIONS Windows: macOS: Linux/KDE Plasma: KDE neon 5.20.5 (available in About System) KDE Plasma Version: 5.20.5 KDE Frameworks Version: 5.78.0 Qt Version: 5.15.2 ADDITIONAL INFORMATION Turning off Baloo entirely makes search work by using the other engine for searches.
How do you turn off indexing but leave baloo on? Which settings specifically did you change? Can you show a screenshot of your baloo KCM? THanks

I'd check whether baloosearch is finding results for you. See if baloosearch yourfilename works. If it does, go back and have look at your Dolphin search, maybe you are hitting the UI confusion; bug 431240 If you have content indexing turned off and you are searching in Dolphin for a filename, you need to click on the "Filename" button (and maybe also "Your Files")
OK so based on that screenshot, it should be indexing filenames only, not content. Cannot reproduce, FWIW. I will echo the suggestion to try `baloosearch` and see if that works.

dominich@dominic-80e5:~$ baloosearch adwaitrecolour Elapsed: 0.449031 msecs dominich@dominic-80e5:~$ ls ~/Downloads/adwait* /home/dominich/Downloads/adwaitrecolour
Update: Upon now changing directory to the Downloads folder, I get this: dominich@dominic-80e5:~/Downloads$ baloosearch adwaitrecolour /home/dominich/Downloads/adwaitrecolour /home/dominich/adwaitrecolour Elapsed: 4.25353 msecs
...and now Dolphin search works, too... weird.
I'm also getting weird behaviour in /, though, despite this: dominich@dominic-80e5:~/Downloads$ cd / dominich@dominic-80e5:/$ baloosearch hosts /home/dominich/Games/sonic-3-angel-island-revisited/drive_c/windows/system32/drivers/etc/hosts /home/dominich/Games/fortnite/drive_c/windows/system32/drivers/etc/hosts /home/dominich/Games/epic-games-store/drive_c/windows/system32/drivers/etc/hosts Elapsed: 1.82707 msecs dominich@dominic-80e5:/$ ls /etc/host* /etc/host.conf /etc/hostname /etc/hosts /etc/hosts.allow /etc/hosts.deny
...and in Dolphin, searching 'hosts' in / produces NOTHING as before.
Some ideas.... ... the results in Comment 6 and Comment 7 don't make much sense to me when put side by side A plain and simple "baloosearch" doesn't mind where you are when you call it, it should give you the same results. If you want to filter results by directory, there is a "-d" option. baloosearch -d Downloads adwaitrecolour You can try balooshow -x ~/adwaitrecolour" and balooshow -x ~/Downloads/adwaitrecolour That will shows you what information baloo has for each file. I'm guessing you might have loads of subdirectories and baloo can hit a system limit. You can what the limit is with: sysctl fs.inotify.max_user_watches If this says 8192 and you've got more than about 8000 folders then the indexing will go wrong. You can increase the limit following: https://bugs.kde.org/show_bug.cgi?id=433204#c12 It may also make sense to purge the database and start again "clean" balooctl purge ... For Comment 9 As above, a plain and simple "baloosearch" doesn't mind where you are when you call it, it looks up its index. If you cd / baloosearch hosts You'll just get hits just from the folders you've indexed. Assuming you've got folders[$e]=$HOME/ in your .config/baloofilerc then you are indexing your home folder and below (and if not specified, that's also the default) You can experiment with telling baloo to index "/" (without indexing file content) but you'll very much need the increase in "max notify watches" ... For comment 10 A search from "/" in Dolphin probably isn't using baloo You can search from "/" is dolphin but it walks through the filesystem looking for things that match - that can take a while (You'll see a "searching" annotation in the bottom right of the dolphin window) Hope I've got this right - and hope this makes sense!
