Microsoft says that the present Online search engine mostly delivers web pages that are not relevant to the content user looking for. (Yes this quote is almost true.)

And Bing helps you harness that information through exclusive tools specific to your key tasks, leading to more-informed decisions. Put simply, Bing is a first-of-its-kind decision engine."
