This may turn out to be a very important tool specifically for research, but really even for basic web searching for detailed information.
From the link:
According to a study by the University of California at Berkeley, traditional search engines such as Google and Yahoo index only about 0.2% of the Internet. The remaining 99.8%, known as the “deep Web,” is a vast body of public and subscription-based information that traditional search engines can’t access.
To dig into this “invisible” information, scientists have developed a new search engine called Infovell geared at helping researchers find often obscure data in the deep Web. As scientists working on the Human Genome Project, Infovell´s founders designed the new searching technology based on methods in genomics research. Instead of using keywords, Infovell accepts much longer search terms, and in any language.
Infovell is being demonstrated at DEMOfall08, a conference for emerging technologies taking place in San Diego on September 7-9. Users can sign up for a 30-day risk-free trial at Infovell´s Web site, and Infovell is initially available on a subscription basis. Later this year, Infovell will release a free beta version on a limited basis without some of the advanced features in the premium version.
