It's one step more, but what I did is on my "apps" screen (my name) off of the lifestyle screen, I simply put the google mobile app there. Tap it and seach box comes up, hit magnifying glass and results come up. Hit exit and you're back to the "apps" screen. If you change your mind, off tapping (i.e. tapping off the google app bar) will close it. It was a very nice compromise for me.
