Yesterday Facebook moved its search beyond the closed social network, so queries typed into its search box give users the option of searching the web, too.

The power behind Facebook's new capabilities is Microsoft's Live Search. The two announced they would partner for search back in July.

The deal includes sponsored search advertising, also powered by Microsoft. Ads that appear in a search are keyword-relevant instead of profile-relevant.

Facebook has an opportunity to do "something cool with social search," but this looks like a typical search engine-content partner deal, according to Mashable. Microsoft gains query volume from Facebook's user base, but it's insufficient to make a dent in the US search market, of which Microsoft sites comprise 8.3 percent (behind Google and Yahoo).

Less than a year ago, Microsoft beat Google in a high-stakes bidding war for Facebook. It managed to secure a 1.6 percent stake (worth $240 million) in the social networking site. It also became Facebook's exclusive third-party ad partner.
