In System Settings, searching for "Update" currently yields no results if the locale is set to German. I would have expected the "Softwareaktualisierung" KCM (kcm_updates) to show up, because the English title "Software update" matches my search query. Currently, the kcm_updates.desktop file has no search keywords. (I changed that in https://invent.kde.org/plasma/discover/-/merge_requests/214.) I think that search queries are also be matched against search keywords of the default locale, additional to the currently selected locale. (e.g. when I search for "screen", many KCMs are showing up in the results) I suggest doing the same with the title (Name attribute in the desktop file).

Git commit 4aab8225fb24a4659b9df6b520ae711bb62f5969 by Fushan Wen. Committed on 02/12/2021 at 23:33. Pushed by ngraham into branch 'master'. Always add English keywords even when the system is using another language 1. FEATURE: Always add English keywords to the list of keywords. 2. Add `doesRemoveDuplicates` bool parameter to `MenuItem::keywords`, so `removeDuplicates()` will not be done in the subitems to improve the performance. 3. Port away from deprecated `KPluginMetaData::readTranslatedString` to `KJsonUtils::readTranslatedString`. 4. Port away from foreach in `MenuItem::keywords`. 5. Add const keyword to `MenuItem::keywords`.
