Baloo search isn't working under Dolphin V15.04.0

I'm using
OpenSuse V13.2-64
KDE Platform Version 4.14.9

I installed Desktop Advanced Search, still doesn't work.

In Dolphin/controls, I have Show-Hidden-Files turned on.
In Desktop Search, I have Enable-Desktop-Search turned on.

I searched this forum for a solution and have some questions.

Q1) I can't find the location of the Baloo files, ~/.kde4/share/apps/config/baloofilerc

What does " ~ " mean with respect to file system?
