Facebook today 15th/Jan/2013, unveiled its new feature that allows users to make "natural" searches of content shared by their friends.
The search allows you to find answers to your social questions like "How many people like in town X jazz music or own an Ipad".

The social graph ( the collective pool of information shared between friends that are connected via the site) will include things such as photos, status updates, location data as well as the things they have "liked".

According to Mr Zuckerberg, the search is not intended to compete with google neither index  the web   but to help you find what you want in the site.

"We look at Facebook as a big social database," said Mr Zuckerberg, adding that social search was Facebook's "third pillar" and stood beside the news feed and timeline as the foundational elements of the social network.

Mr Zuckerberg said that graph search would launch immediately as a beta test, and would roll out "very slowly". The tool will be usable from the blue banner that sits at the top of every Facebook page.

 

"We're going to put an encouragement on the home screen of everyone's account so that everyone has the chance to look through these tools.
