Bug ID: 459586
Summary: Application Launcher and KRunner should strip away

Classification: Plasma
Product: krunner
Version: 5.25.5
Platform: unspecified

Example of stop words (like "to") yielding a bunch of unhelpful keyword matches
in Application Launcher
SUMMARY
If stop words (https://en.wikipedia.org/wiki/Stop_word) are filtered out of
search queries, results would be much better.
When one is using the Application Launcher or KRunner to query for `1000 USD to
EUR` (for example), the `to` part of this query matches various unrelated
things like "Display Configuration", "Night Color", "Device Actions",
"Autostart", "Windows Shares", etc.
While the ordering of the actual results differs (it's better in KRunner than
in Application Launcher, courtesy of
https://bugs.kde.org/show_bug.cgi?id=431204), both suffer from the same problem
of matching things that they'd better not match at all.
STEPS TO REPRODUCE
1. Open Application Launcher or KRunner
2. Query for `1000 USD to EUR`
OBSERVED RESULT
There are various unnecessary results that appear to be matches to the `to`
keyword.
EXPECTED RESULT
Stop words (like `to`, `the`, etc.) could be stripped away from keyword-based
queries.
