Bing has made a big and bold move. If now a user searches for some long tail queries such as specifications for black iPhone 6 64GB, Google maps local intent pack or others, Bing may display only one page of search results.
Bing will say the reason of this step is that they want to deliver 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 snapshot of the footer of the Bing search results page:
