Ok, I did a test. "zero to one" in Google - all results on the first page are book related. In Bing - not even ONE result is about the book, instead I got things like "0 (number)" (Wikipedia), "nhibernate - Modeling one to zero or one" (a stackoverflow question), a clock named "onezero", "Zero Hour" movie on imdb...
It's in 'related searches' but that's it.
Not book related results are ok, but not even one book related link in the first five pages? I think I will stay with Google for now.
(I did this in private mode to disable Google search personalization).
edit: Ok, Bing starts showing the book when I change location to United States. Default results are these [0]. Seems they really need to work on their location-related personalization, these results are complete trash.
