iOS/Web: Facebook's Graph Search uses keywords to bring back old content that's been shared with you. This new update will help you find things you remember reading but can't find again, and it's rolling out to iOS and desktop users.
Using search, you can plug in keywords to review old content that was previously shared to you, so it doesn't open your content up to the public. Just go to the search bar and type in keywords such as "Mary's wedding photos" or "Funny French Bulldog", and you'll find what you're looking for. It's strange this feature wasn't already available, but at least now you'll be able to find that post you were reading before you refreshed your news feed.
The update is rolling out to all desktop and iOS users this week. There is no word yet on an Android rollout. Hit the links below for more information.
