MetaCrawler

MetaCrawler is a metasearch engine that blends the top web search results from Google, Yahoo!, Bing, Ask.com, About.com, MIVA, LookSmart and other popular search engines. MetaCrawler also provides users the option to search for images, video, news, yellow pages and white pages. MetaCrawler hit its stride in the late 90's 

MetaCrawler was developed in 1994 at the University of Washington by studentsErik Selberg, Bobby Kalili, and Professor Oren Etzioni as Selberg's Ph.D. qualifying exam project. Originally, it was created in order to provide a reliable abstraction layer to early Web search engines such as WebCrawler, Lycos, and InfoSeek in order to study semantic structure on the Web. However, it became clear that it was a useful service in its own right, and had a number of research challenges.
