Microsoft is expanding its search arrangement with Facebook but reining in its advertising deal with the social-networking site.

Bing already runs search on Facebook in the U.S. But on Friday, Microsoft said Bing would also provide search results for all of Facebook's 400 million users around the world.

Microsoft also said that it would offer Facebook users additional Bing features, although it did not describe which. "Our two companies will soon provide Facebook users with a more complete search experience by providing full access to great Bing features beyond a set of links, including richer answers combined with tools that help customers make faster, smarter decisions," Jon Tinter, general manager for Bing, wrote in a blog post.
