Thanks! I looked at the Baloo control panel application. It lets me exclude
directories, but I could not find any way to exclude USB and network
connected drives. I have a lot of symlinks in my home directory pointing to
a directory in another folder also in my home directory. I wonder how baloo
treats symlinks? If you know how I can get Baloo to only index my home
directory (and possibly ignore symlinks) it would be great. I have look at
the baloo configuration file. Not too complicated, but again I have no idea
how to disable USB and networked drives. Some of those are not mounted at
all times and most of them through Dolphin. Again, if I could get baloo to
only index my home directory and ignore everything else I assume I will be
fine.
Finally, if I disable baloo can I still use Plasma Search (Alt-Space). Love
that thing and use it for everything.
