On kde dolphin or kfind, there is a powerful search tool, it supports regex, and it’s recursive on the directory where dolphin is pointing to.
On “open document” window dialog that is used with all QT apps ( kate, dolphin… ) when opening a file, i am looking for a way to perform searching inside a directory, but i only found filter option via Ctrl-I but this one is not recursive and doesn’t support regex.
Such feature would provide better UX, instead of going inside heavily nested directories or performing the search in another app like kfind or dolphin.
Thank you.
