For those who can not remove the Search Bar from the Home Screen, I found a way to do it.
This is for CyanogenMod 11, KitKat 4.4.3 Build 14/06/2014:
On the Home Screen, you press and hold the screen, untill the "wallpapers/widgets/themes" options come out.
When that happens, press the three dots that look like an arrow, it will open another menu with lots of options to change.
There, the first option you can change is the Search Bar, turn it off. Press the three dots again to minimize the menu, hit back and that's it.
Hope this helped.
