Facebook confirmed they will no longer use Bing! Search results on the social network, after eight years being the predominant service for Facebook.

The move comes as Facebook gets more interested in search, recently adding a new feature to search individual posts on the site. Facebook is actively working on more technologies to advance search, both inside and outside the social network.

Microsoft originally set up a deal with Facebook in 2007 to add Bing! Search and renewed the deal in 2010. It should be noted Microsoft in 2007 also invested $240 million, valuing the social networking site at $15 billion. Facebook is now worth over $200 billion and continues to grow as stock's rise. Even though Microsoft gave them the financial kick, it looks like Facebook does not see an unbreakable partnership.

Bing! Search has been optimized in the past few years, but still lags behind Google in terms of relevance or revenue. In Europe, Google owns over 90 percent of the search market, in the U.S. it is a little lower.

Microsoft has lost quite a lot on Bing, including a $6.3 billion write-off after acquiring advertising site aQuantive. Facebook re-launched one of aQuantive's three subsidiaries, Atlas, a few months ago for next to nothing.

Under the leadership of Satya Nadella, it looks like Microsoft is moving away from search. The company recently fired all of its search advertising staff and has not been renewing Bing contracts or advertising the search network.

Microsoft often likes to stay in a market, even if it is not doing well, but the new drive by Nadella is removing any of the flak. Microsoft is fully focused on cloud, services and enterprise, the three main markets.
