Add a tutorial for baloo in KDE welcome program

Yes. I know that. I’m not just talking about source file index, I’m talking about a more general user-experience.

Just look at this topic: Cannot properly use Baloo. You see, baloo doesn’t work for this guy as excepted and he finally decides to give up.

Also look at this guy in reddit https://www.reddit.com/r/kde/comments/1bqjia9/is_this_normal_for_baloo/. Instead of reporting a bug to upstream, he or she also ends up disabling baloo which actually make baloo get into a vicious circle. I’m not blaming him, a regular user who doesn’t want to spend lots of time tinkering software makes sense.

So besides documents, should we provide a user-friendly interface like tips of the day in Kmymoney and libreoffice to “teach” them how to use baloo index and report bug correctly when something goes wrong if providing one in welcome program isn’t satisfied?

Due to multiple possible combination of Filesystem under Linux, baloo can just use a much more generic way to index file and maintain index database itself instead of relying on filesystem itself like what Everything does under Windows platform. So there might be lots of bugs behind it because of this kind of complexity.
