On UbuntuStudio 14.04 Dolphin Search Option Not Working - Help

[WMID]

I use UbuntuStudio from 12.04 (x86), now I install 14.04 but the  dolphin
search option not working. I search on the web to find how to solved this,
I found that the search engine are to change, but do not find nothing to
solved this. Do you can Help my

Note: baloo are installed by default. The version of Dolphin is 4.13.0

I can not use other File Manager because Dolphis is very flexible,
customizable, and have very high options. And Dolphin is very well suited
to my monitor with 1024x768, the fonts fit well on the monitor, Dolphin for
my is the best (only not have dropbox integration, to this I use Nautilus)
