I've been using GEL exclusively since the 4.4 update rolled and other than a couple of things that I miss about wallpaper re-sizing, etc from Nova, it's been working great. I don't recall the exact process, but I think it was pretty close to as simple as installing the Google Search APK, but I'm not sure that it's not already part of the search app that we have straight from Moto, because I don't have a separate icon for it anymore in my app drawer.
