I published a blog on Microsoft search and it has been quoted by many
“This is one area where Bing has a clearly better user experience than Google, if you’re looking to get actionable results from the actual search box. While Google will put a Pitbull Google+ profile in its autosuggest feature, it does little with suggestions for any of the examples Bing provides.
That’s not to say Google’s Knowledge Graph results don’t provide ways for users to distinguish what they’re looking for, but you have to get through the search query before you can tell Google what you’re actually looking for (like the Harry Potter books vs. movies, for example). Of course, you could always specify in your actual query.”
