I've tried switching to Bing (kinda forced on a Lumia) and also sometimes when I can't find what I'm looking for with google. Without fail I've found myself switching back from Bing almost instantly even if I'm stuck with IE.
You probably are in the US. Outside that, bing just cannot find anything.
Anyway i also have a lumia but I set google as search engine in ie mobile
+1 here
You read my comment wrong. I am saying that Bing is useless. I did the same with my Lumia but still some actions default to Bing.
