Yahoo

Yahoo Search is a web search engine, owned by Yahoo Inc., and was as of January 2014 the second largest search directory on the web by query volume, at 5.45%, after its competitor Google at 71.36%, according to Net Applications to compete with Microsoft Corporation's Bing search engine.

Yahoo Search, originally referred to as Yahoo provided Search interface, would send queries to a searchable index of pages supplemented with its directory of sites. The results were presented to the user under the Yahoo brand. Originally, none of the actual web crawling and storage/retrieval of data was done by Yahoo itself. In 2001, the searchable index was powered by Inktomi and later was powered by Google until 2004, when Yahoo Search became independent.

On July 29, 2009, Microsoft and Yahoo announced a deal in which Bing would power Yahoo Search...
