I’ve only been using KDE for a couple of months now, and read enthusiasm for Krunner as a search tool, but I’m yet to be convinced by this.
To start with I see Dolpfin has a ‘search’ facility under menu tab ‘Edit’. But so far I’ve failed to find one file using that. No files matching search - is the usual response even when there are relevant named data files within the path of the opened folder, so that method is useless.
As for a direct Krunner search (Alt+Spacebar), that’s a bit more succesful when searching for a file, but it doesn’t find them all. Eg, when using the locate command for files with name of ‘Audacity’ included within, 9 files (correct number) are listed, whereas Krunner finds 8 files. The missing file is on a slightly different path compared to the other 8, but no reason why it’s not picked up.
I installed Catfish, an Xfce file search tool which I found also works well with KDE. And as with the ‘locate’ command it finds all the files.
So I’m not stumped when it comes to doing a file search by a method that I know I can trust. However, I don’t know why Dolphin’s search tool never seems to work, nor why Krunner does not produce reliable results.
