Days after Facebook announced an update to Graph Search, reports have began to surface that Facebook has removed Bing as its primary search engine. One news agency suggests that Facebook will announce a new Web search engine Monday.

"We're not currently showing Web search results in Facebook Search because we're focused on helping people find what’s been shared with them on Facebook," per a Facebook spokesperson.  "We continue to have a great partnership with Microsoft in lots of different areas."

While Graph Search focuses on helping people find what has been shared with them on Facebook, the new tool will search across the Web similar to Microsoft Bing -- which now, along with Yahoo, holds about 30% of the search market in the United States.

Industry researcher comScore said that as of October, Google represented 67% of Web searches, followed by Microsoft's Bing with nearly 20% and Yahoo Sites with 10.3%.

While Bing may not support Facebook users across the Web, it still powers Apple Siri and Spotlight search on mobile devices. Spotlight allows users to search for content stored locally on an iPhone and with iOS 8, as well as results from apps such as Apple Maps, iTunes, the App Store, and from the Web. It was announced at Apple's most recent iOS conference.

At the most recent MediaPost Search Insider Summit in Park City, Utah, industry experts debated Google's and Facebook's position in search engine marketing for desktop and mobile. Some believe Facebook will overtake Google's No. 1 search position in 2015.
