[Search] Changed search load time

Changed how frequently the search controller
checks for updates. This makes the load icon
dissapear faster, and looks more natural. But,
may affect performance.
Also changed the point at which the loading
status becomes 'true'. Made it earlier, at
the beginning of the controller's update().
