Facebook unveils search engine for 1 billion people

NEWYou can now listen to Fox News articles!

The world’s biggest social network has unveiled a new search engine to let you pore through the 1 trillion connections linking its billion users.

At an event in California -- the company's first major product launch event since its May initial public offering -- founder Mark Zuckerberg announced Graph Search Beta, which the company says will make the world more open and connected by letting people navigate their connections.

“When Facebook first launched, the main way most people used the site was to browse around, learn about people and make new connections. Graph Search takes us back to our roots and allows people to use the graph to make new connections,” the company said.

The new search engine will appear as a bigger search bar at the top of each page. Type in a few words -- “photos I’ve liked” or "friends of friends who are single in San Francisco" -- and the page will instantly refresh with results from the site.

Zuckerberg said the search engine was built to maintain privacy settings that users have already set. And he stressed that Graph Search is not an Internet search engine that competes with Google.

"We are not indexing the web. We are indexing our map of the graph, which is really big and constantly changing. Almost a million new people every day. 240 billion photos. 1 billion people. 1 trillion connections," he said.

Graph Search is available in English today for a limited number of users, and it indexes only a subset of content on Facebook.
