Do you know what the AwesomeBar search about, it relies on your history to be fully functional. It takes about three weeks of history for it to really work well, and from the sounds of it you just destroyed your history. The '''AwesomeBar''' search is what you get in the location bar drop-down when you enter strings of characters that exist in the Title and/or url address of a previously visited site or one that you have in your bookmarks. You see those choices '''before''' you press "Enter". Once your press "Enter" by default you would do a search with your currently selected (default) search engine, as if you had entered the search into the search bar.
