Facebook unveils social search feature Graph Search

Facebook CEO Mark Zuckerberg has unveiled a new search feature on the world's biggest online social network.

Called "graph search," the new service lets users search their social connections for information about people, interests, photos and places. Until now, Facebook users were unable to search for friends who live in a certain town or like a particular movie. With the new feature, people can search for friends who, say, live in Boston who also like "Zero Dark Thirty".

There are over 1 billion people on Facebook, over 240 billion photos, and 1 trillian social graph connections, according to The Next Web.

Facebook says Graph Search will appear as a large search bar at the top of the page that will offer search suggestions when you begin typing. It will also display results on a page that you can filter and customize.

Zuckerberg says the search feature is "privacy aware." That means users can only search for content that has been shared with them.
