News from Facebook blog, says that graph search will include post and status updates, and it started yesterday.
This means you will be able to search for status updates, photo captions, check-ins and comments to find things shared with you. Not forgetting topics you’re interested in and see what your friends are saying about that particular topic, even posts you commented on before can be searched with this development plus your posts from last year.
You can even search for posts about cities, places from a certain time like posts from last month by friends or posts written by a certain politician or from the Parliament.
It should be noted that as with other things on Facebook, Graph search can only see content that has been shared with you including posts shared publicly by people you are not friends with. With this, Facebook says use privacy shortcuts and Activity Log to review who can see the things you share.
As for now this development is rolling out slowly to small groups of people who are currently using Graph Search and we will continue to improve this experience by listening to feedback.
Learn more about looking for posts with Graph Search on Facebook through their the Help Center.
