Mark Zuckerberg took time out of this morning's presentation to highlight one Graph Search partner in particular: Microsoft Bing. According to the CEO, the company has teamed up with Bing "to show you world class search results for things that don't match your query." It's essentially to supplement Facebook's search results with information that it may not already have as part of its user profiles: weather, music results, and the like. Bing results show up as traditionally-formatted blue web links, standing out clearly from the rest of the Graph Search results.

"We don't think a lot of people will come to Facebook to do web searches," Zuckerberg said, "but if we can't find what you're looking for, it's good to have this." Facebook's Graph Search launches today in a limited beta.
