INTRODUCING GRAPH SEARCH FACEBOOK

Woow!!Today facebook has launched its beta phase graph search. With Graph Search, you simply enter phrases such as "My friends who live in Ghaziabad," "Photos of my family taken in Kanpur," or "Dentists my friends like," and Facebook quickly displays a page of the content you've requested.
                                                                                                      In Facebook's early days, people could search for basic things like friends, groups, and events, but the systems that powered these searches weren't comprehensive, nor were they able to scale with the site's growth.

The prototype

This project presented two parallel challenges: what would such a product look like, and what infrastructure would we need to build to support it?

For the product part, they discussed and debated, and built several simple prototypes of graphical UIs that allowed users--click-by-click--to build up structured, database-like queries. But they all seemed too complex and not quite up for the full scope of Zuck's challenge to them.

Then an idea emerged around the title of each page on Facebook. They(graph search engineer) wanted people to be able to construct their own views of the particular Facebook content they were interested in. If a person simply entered the title of the content they were looking for, could we then build a system that would understand the searcher's input and find the content for them?

Privacy

When you share something on Facebook, you get to decide exactly who can see that content. This, of course, is why Graph Search is such a powerful experience: a lot of what you will find is content that is not public, but content that someone has shared with a limited audience that happens to include you. It is also part of what makes Graph Search an interesting technical challenge for us. The system has to do an extraordinary amount of privacy checking in real time to deliver the experience we want.

Future

Today's Graph Search beta is just the beginning. They're starting with a focus on people, photos, places and interests, but are looking forward to incorporating posts and Open Graph actions, as well as making Graph Search available on mobile and in every language and are very excited to be able to keep making search more useful, fun and central to how you explore existing connections and make new ones on Facebook.
