A search start-up called Infovell has renamed itself DeepDyve, begun offering a free "deep Web" search tool, and expanded its search technology to the domains of computing, clean tech, and energy.
Infovell announced its search business plans in September, with search technology for the domains of biotechnology, pharmaceuticals, patents, and Wikipedia. Now the search site has begun expanding into physical-science areas.
DeepDyve is designed to reach areas of the Internet not indexed by Google, Yahoo, and other major search engines, the company said. The company has indexed 500 million pages so far and hopes to expand to 1 billion by the end of the year.
The free DeepDyve technology requires registration, and the more elaborate premium product, which offers more complicated visualization and filtering of search results, costs $45 monthly per user.
