I found the following sentence in kcontrol_baloo.pot: By default <guilabel>Enable File Search</guilabel> is activated, uncheck this setting if you want to use the file search at all.
I my view there are contradicting things in this sentence. Either the default is deactivated or "if you want" should be "if you do not want" -- vr.gr. vertaler van KDE Freek de Kruijf
