Looks like a communication extension that moves your site's search feature up into the AdWords ad... makes me wonder if it's a beta for folks who use G as their site search vendor (makes sense they'd start there).
If in early beta, it's likely those playing are gagged by NDA, suggest you talk to your G rep for more info. I haven't read anything about this, so i'm guessing it in early, gagged beta phase now.
Can def see it on your suggested search.
