Yahoo Search Engine

Yahoo! Search is a web search directory, owned by Yahoo! Inc. and is the 2nd largest search directory on the web by query volume, at 6.42%, after Google at 85.35% and before Baidu at 3.67%, according to Net Applications.

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.

Seeking to provide its own search engine results, Yahoo! acquired their own search technology. In 2003, Yahoo! Search became its own web crawler-based search engine, with a reinvented crawler called Yahoo! Slurp. Yahoo! Search combined the capabilities of all the search engine companies they had acquired, with its existing research, and put them into a single search engine. The new search engine results were included in all of Yahoo!’s sites that had a web search function. Yahoo! also started to sell the search engine results to other companies, to show on their own web sites. Their relationship with Google was terminated at that time, with the former partners becoming each other’s main competitors.

In October 2007, Yahoo! Search was updated with a more modern appearance in line with the redesigned Yahoo! home page. In addition, Search Assist was added; which provides real-time query suggestions and related concepts as they are typed.

In July 2008, Yahoo! Search announced the introduction of a new service called “Build Your Own Search Service,” or BOSS. This service opens the doors for developers to use Yahoo!’s system for indexing information and images and create their own custom search engine.

In July 2009, Yahoo! signed a deal with Microsoft, the result of which was that Yahoo! Search would be powered by Bing. This is now in effect.

Yahoo! Search also provided their search interface in at least 38 international markets and a variety of available languages. Yahoo! has a presence in Europe, Asia and across the Emerging Markets.
