I was expecting krunner (and maybe the other Launchers like Application Launcher, Application Menu, Application Dashboard) to find files the way Synapse does or even Whisker menu. For some time these Plasma tools have searched and found only files and folders in $HOME, and even there they still find no links. (The only thing that krunner does more than the rest is to show "Places".)
How is Krunner supposed to find files?
Is it supposed to search for files and folders outside $HOME?
Should I type something like "search" or "locate" before typing the name of the searched item?
On a separate drive some files and folders are seen, but not all of them. What is the difference between the ones that are searchable and the rest? Could it be the depth of directory levels?
I see posts saying that it should find files, like this, albeit complaining that it does not as expected.
But, before complaining that it does not, I would like to know what is the way in which the search should be made.
