This is a bold move by Bing! If you search for some long tail queries such as [specifications for black iphone 6 64GB], [google maps local intent pack] or others, Bing may show you only one page of search results.
Not only that, Bing will say the reason they are only showing one page of search results is because they think they are showing you the "most relevant results for your search" and decided to take the liberty to omit the "lower-quality results" from the search results page.
Here is a picture of the footer of the Bing search results page:
We think these are the most relevant results for your search. We've omitted some lower-quality results. See all results.
Typically it would look like this:
Pretty bold and cool of Bing, don't you think?
