Facebook and Microsoft have had a long-standing relationship, which for quite some time has led to Facebook including Bing results in the Facebook search bar. Similarly, searching in Bing would allow Facebook users to find results from their friends. However, it appears that Facebook has been making some changes regarding the way their search function works. In particular, it looks like they have removed Bing from the equation, without fanfare.
One of the reasons that Facebook worked with Bing in the first place was because it has long considered Google to be a rival, especially with Google’s mostly unsuccessful plunge into social network territory with Google Plus. What this means for the future of the partnership between Facebook and Bing is currently unclear, though it is likely that these changes have been made in relation to Facebook’s new search functions, which I talked about last week.
It seems that Facebook wants to refocus their search functions to work within Facebook, rather than extending to the rest of the web. However, the refining of their search functions appears to be used to compete with other search experiences. A Microsoft spokesperson says that they continue to partner with Facebook in other areas apart from the search function. It still is possible that Facebook and Bing will work concurrently in the future, but under what circumstances is currently unknown.
