Its powered by Bing which is meh but I don't mind it so much. If I don't get good results I throw in "#g" in my search and it will run the query with Google.
honestly, i'm using for a week and i'm a pretty technical person, i always get good results searching about technical issues and linux(thats a pretty niche too) i can't complain, but maybe with others affairs it's isn't so good?, anyway good to know about that shortcut
The first 20ish results of Google are either shops, YouTube or Google just struck out words of my search on it's own. Google search has already been ruined by them.
