Facebook issued a statement Monday denying theto partner on search solutions.
"People expect a better search experience on Facebook. We are working on improvements to better meet those expectations but are not in talks to enter into a new search partnership," a company spokesperson said.
This story came from The Sunday Telegraph, alleging that Mayer and Sandberg were plotting an alliance around search, citing unnamed sources at the board of directors level.
The statement didn't address whether the two former Google executives are talking about other strategic issues. Yahoo has been a longtime partner of Facebook, integrating data from the Facebook social graph into various products.
Both Facebook and Yahoo are working with Microsoft's Bing search engine. Yahoo has a long-term contract to use Bing for its search results, and Bing integrates data from Facebook's social graph into its search results.
