Facebook debuts a new search tool

Keeping users on site a big goal

NEW YORK — Facebook on Tuesday took a stab at cracking a big problem of its own making: how to help its one billion users find what they’re looking for in the jumble of posts, pictures, and blue thumbs-up ‘‘likes’’ they share every day.

At company headquarters in Menlo Park, Calif., Mark Zuckerberg, cofounder and chief executive, announced a tool Facebook had spent over a year honing. He called it ‘‘graph search,’’ and said it would be available to a limited number of users on Tuesday and gradually rolled out to the rest. It will enable users to search the social network for people, places, photos, and things that interest them.
