Finally, Facebook is updating it’s search functionality with “Graph Search”.

Facts: Facebook currently has more than a billion users with more than a trillion connections. And there are more than 240 billion fotos published on facebook.

Graph Search is a new way for you to find people, photos, places and interests that are most relevant to you on Facebook. Technically it is a high-speed contextual discovery engine.

Graph Search will help you instantly find others, learn more about them and make connections, explore photos, quickly find places like local attractions and restaurants, and learn about common interests like music, movies, books and more. All results are unique based on the strength of relationships and connections.

“It is not web search,” Zuckerberg says.

Graph Search and web search are completely different. Web search is designed to take a set of keywords (for example: “music industry”) and provide the best possible results that match those keywords.
With Graph Search you combine phrases (for example: “my friends in Los Angeles who like Justin Timberlake”) to get that set of people, places, photos or other content that’s been shared on Facebook.

Facebook is taking privacy more serious
Another big difference of Facebook Graph Search is that every piece of content on Facebook has its own audience, and most content isn’t public. Facebook built Graph Search from the start with privacy in mind, and it respects the privacy and audience of each piece of content on Facebook. It makes finding new things much easier, but you can only see what you could already view elsewhere on Facebook.
