Facebook to buy shopping search engine TheFind for undisclosed amount

Facebook, the US-based social network, said it bought shopping search engine TheFind to help boost its advertising business.

Facebook did not disclose the terms of the deal, but said in a statement on Friday that TheFind would help make the website's ads better and more relevant for its users.

The acquisition is expected to close in the next few weeks.

"We are joining Facebook! This means we'll be taking our search engine and apps offline effective 3/13/2015. Thanks for your loyalty," TheFind wrote on its Twitter profile description.

TheFind, which was founded in 2006, will shut down and some of its key employees will work at the social network. The Mountain View, California-based website lets users search for items to buy from websites or in local stores.

Shares of Menlo Park, California-based Facebook slipped 5 cents to $78 after the international stock market closed.
