Facebook has overhauled its internal search engine to allow members to easily search through their friends' profiles.
Facebook unveiled its Graph Search at an event in Palo Alto, California, which will initially allow its members to search the social network's database of people, photos, places and interests.
According to the Telegraph, Mark Zuckerberg emphasised that the system did not allow members to search the web outside Facebook, quashing speculation before the event that it aimed to compete with Google more directly.
Graph Search allowed Facebook members to query Facebook using natural language rather than keywords.
Zuckerberg said its creation had been 'really hard' technical challenge for engineers that have been in development for more than a year, the report said.
He gave the example of a simple search such as 'who are my friends in San Francisco'.
It quickly returned a list of Zuckerberg's friends in the city, ranked by how close his relationship to them is, with his sister at the top.
Facebook executives emphasized that Graph Search complies with members' existing privacy settings.
For instance, if someone has set a photo to 'friends only' it will not appear results of a search for 'photos of friends of friends' by a member who is not their friend, the report said.
He also introduced new privacy tools alongside Graph Search, including the long-awaited ability to untag themselves in photos in bulk, the report added. (ANI)
