...we're rolling out a new version of Search to everyone on the site beginning today.
You now will be able to search the last 30 days of your News Feed for status updates, photos, links, videos and notes being shared by your friends and the Facebook Pages of which you're a fan. If people have chosen to make their content available to everyone, you also will be able to search for their status updates, links and notes, regardless of whether or not you are friends. Search results will continue to include people's profiles as well as relevant Facebook Pages, groups and applications.
To search for a particular term, just enter your query in the search box in the upper-right corner of any page. Once you're taken to the search results, use the filters on the left-hand side of the page to view only posts by friends or posts by everyone. If you're searching for a specific person, Page, group or application, you also can filter by those results.
