Facebook has indexed almost two trillion posts of its members, making it easier to find search for a certain post.
The new plan of Facebook is designed to attack Google's core business and challenge Twitter's news product. It will let the users search for particular topic and be given a bunch of public posts dating back to Facebook's inception.
This new change means that many older posts will now be added to results when people search for news or information. Tom Stocky, the social networking giant's vice president of search, said that this is an attempt of the company to keep people on the site rather than go elsewhere to keep up to date with events, BBC reported.
Facebook hopes that the tool will allow it to become more of a way of finding out what is going on, making it possible to search for how people are reacting to a news event, for instance, or to find everything that everyone has said about a certain TV show. It will also allow Facebook to track more accurately what people are talking about, so that its search tools can offer information about what’s going on.
Facebook's search function will be able to surface old content, even posts that users may have done years ago could be found. This of course raises questions about privacy. People who don't want any future posts to appear on search can make them private.
Users have an option for hiding posts. Under the Settings bar, they can click “See More Settings” and bringing them to “Who can see my stuff?” option, where privacy options can be changed. There is an option to “Limit Past Posts,” making every status ever posted available only to friends, at the same time hiding it from the new search, according to CNBC.
