Yippy

Yippy is a Deep Web engine that searches other search engines for you. Unlike the regular Web, which is indexed by robot spider programs, Deep Web pages are usually harder to locate by conventional search. Thats where Yippy becomes very useful. If you are searching for obscure hobby interest blogs, obscure government information, tough to find obscure news, academic research and otherwise obscure content, then Yippy is your tool.
