Added the current extent of the map as a search filter and showed the result's type, city, and country next to the result's name.
I have also enabled searching without a spatial bound to avoid an incorrect report of "no results found", e.g. searching for well known cities, states, or countries like "California" when the map is zoomed to a small city somewhere in Africa, should yield some hits.
Referenced version 10.2.3.
