Updated with official info from Facebook.
Facebook will launch its upgraded search engine Monday.
Originally announced in January 2013 and dubbed Graph Search, the new search engine lets you search your Facebook social graph for people, places, photos and interests.
With the new search engine, users will be able to ask specific questions, such as "which of my friends live in New York?" Graph Search is also integrated with Microsoft's Bing, meaning it will offer web search results if it can't find anything useful in your graph.
Facebook also claims the new search engine is faster, easier to see and use, and it picks relevant results better than the current one.
Facebook users who have the language set to U.S. English should start seeing the upgraded search box today.
While the mobile version of the Graph Search is still not available, Facebook claims it's working to get it ready as well.
We're very interested to see how the Graph Search works in practice at this stage, and we'll have a detailed rundown when it arrives.
