Facebook has just implemented a greatly expanded real time search of over two trillion posts as documented in links below. Users who have an extensive history of posts may wish to move some items from public to private viewing as formerly obscure posts could become more visible in the expanded search.



Facebook is ready to challenge Google and Twitter for control of real-time news search and the news itself. Starting today with a rollout to US English language users, Facebook Search will return anything you’re allowed to see from its 2 trillion posts. That includes public posts by all people and Pages, not just your friends and Pages you Like as before. The personalized results will be broken up to highlight posts from trusted news sources, followed by people in your network, lists of the most popular links or quotes about a topic, and then strangers.

Facebook Search SummarySimilar to how Twitter Search works, this move unlocks all the news and chatter shared on Facebook around big news stories and live events, but with a more human focus. Not only could this make Facebook a place people look for perspectives on the news. It could in turn inspire more people to post publicly about what’s happening in the world, since there will be more ways to discover that content than in the feed.

Though the privacy of people’s posts isn’t changing, everything you’ve ever said will be much easier to find now. That means an off-color joke from years ago and the wrong privacy setting could combine to get you in trouble with your employer. I think Facebook could do more to communicate to users that they should go back and check what they’ve shared publicly, run searches on their own name with some offensive terms, and hide anything problematic from the public.
