Facebook recently updated its Graph Search tool to make it easier to find friends' old posts. According to Reuters, though, the company failed to announced another change: it has apparently stopped showing Bing results, as well. The social network launched Graph Search in 2013, giving people a quick way to scour the website for posts, pages and users. It could also be used like a typical search engine (thanks to Bing), so you could, theoretically, research for a school paper without leaving the website. Both companies have confirmed the change to VentureBeat, even saying that it was implemented a while ago.
