Today Facebook was awarded a patent for “ranking search results based on the frequency of clicks on the search results by members of a social network who are within a predetermined degree of separation”. The patent, which was first filed by in 2004, emphasizes that Facebook has been working on a number of algorithms to improve their search results, one of which is a tool that Google employs in their own search results: the number of clicks.
Today, Facebook is starting to roll out a new feature in their search bar that incorporates more results relevant to your network’s connections. Engineer Wayne Kao wrote on Facebook’s blog today that the site will be serving up more search results, and to do so, they’ll leverage your social graph. The aim is to surface more information while maintaining relevance.
