Bug 442431

Windows:                not tested
macOS:                  not tested
Linux/KDE Plasma ------------------------------
SUMMARY

The "Desktop Search" plugin of KRunner yields outdated results for
file name based search compared to running "baloosearch" at the
terminal.


STEPS TO REPRODUCE (does not always work, see “ADDITIONAL INFORMATION”)

1. Configuration
1.1. Enable “Desktop Search” in KRunner.
1.2. Ensure that Baloo indexes ~/Documents

2. Creation of new file.
2.1. Run: “touch ~/Documents/'2031 - User et al. - Baloo is faster.pdf'”
2.2. Test “baloosearch 2031” and searching for “2031” with KRunner.


OBSERVED RESULT

“baloosearch 2031” instantly shows the newly created file, whereas
typing “2031” into KRunner or Application Launcher does not show the
file.

After a while the file will also be shown in KRunner.

After deleting or renaming “~/Documents/2031 - User et al. - Baloo is
faster.pdf”, “baloosearch 2031” will instantly stop returning the
result, while “KRunner” will still show the now outdated result.


EXPECTED RESULT

KRunner should update its result as fast as Baloo.


SOFTWARE/OS VERSIONS
Operating System:       openSUSE Leap 15.2
KDE Plasma Version:     5.18.6
KDE Frameworks Version: 5.71.0
Qt Version:             5.12.7
Kernel Version:         5.3.18-lp152.87-default
OS Type:                64-bit


ADDITIONAL INFORMATION

After a reboot the issue went away, but I expect it to return, as it
always did so far.

In the past I’ve also seen search results being updated after waiting
for a long time, without rebooting -- but I can’t be entirely sure
anymore.

The issue was reproducible over the last 2 years in Application
Launcher and KRunner. The conditions under which (temporarily)
real-time updates work are not clear.
