Yahoo Search

Yahoo Search

Yahoo! Search is a web search engine, owned by Yahoo!, Inc. and is currently the 2nd largest search engine on the web (as defined by a September 2007 Nielsen Netratings report.)

Originally Yahoo! started as a web directory of other websites, organized in a hierarchy, as opposed to a searchable index of pages. Over time, Yahoo! evolved into a full-fledged portal in the late 1990s with eventually a Search interface.

"Yahoo! Search" originally referred to a Yahoo! provided Search interface, which 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.
