Search Engine Dives into the Deep Web

Kara Reeder

A research-focused search engine is claiming to go where no search engine has gone before: the deep Web.


Founded by Human Genome Project scientists, DeepDyve searches the 99 percent of hits not picked up by other search engines, like content hidden behind paywalls or not linked to enough sites to gain ranking. According to Wired, it does this by using an algorithm called "KeyPhrases" to index passages up to 20 words in length. DeepDyve also can search up to 25,000 characters.


The search engine, previously known as Infovell, focuses on life sciences and has just added IT, clean technology and energy content, reports eWEEK. It is available via subscription or as a free ad-supported version.
