Facebook said in a blog post announcing the tool that only the user can see the search result data, in a bid to quell some privacy concerns.

It would allow users to jump back in to their recent searches -- from people and places to interests and pages -- and delete each search or wipe the lot with one click of a button.
Facebook announced, Graph Search, in January. The social network billed the feature as the new way to find people, photos, places, and the like.
