Besides Photon there is Mapzen search that provides search as you type. Naturally comparing with google is a bit apples and oranges, on the one hand a company that purchases essentially all its data and spends billions on its mapping department, compared to the OSMF with a annual budget of roughly $150k. So it is not a surprise that some things take a bit longer with OSM, but it is tortoise vs. hare....
