Today Facebook launches its search engine's newest upgrade. This upgrade called 'Graph Search' was annouched in January 2013. With this search tool Facebook users can ask specific questions to their search bars, such as which of their Facebook friends live in a specific area or went to a certain university. The search engine is also paired with Microsoft's Bing, so the search can offer web results if nothing comes up in your Facebook graph. All users with the English language setting should start seeing this upgrade in effect today.
