Your friends have shared their life with Facebook. Now, Facebook is making sure you can actually find what they’ve shared.

The social network unveiled a new search tool, Graph Search, that Facebook chief executive Mark Zuckerberg described as the “third pillar” of Facebook, alongside News Feed and Timeline.

Graph Search, which is initially launching in beta as a limited preview for U.S. audiences only, will allow users to uncover social connections between other members of the site and quickly identify which friends have been to certain places, “liked” specific topics or appeared in certain photos.
