Darpa Is Developing a Search Engine for the Dark Web - Kim Zetter, Wired

The project, dubbed Memex, has been in the works for a year and is being developed by 17 different contractor teams who are working with the military’s Defense Advanced Research Projects Agency. Google and Bing, with search results influenced by popularity and ranking, are only able to capture approximately five percent of the internet. The goal of Memex is to build a better map of more internet content. http://www.wired.com/2015/02/darpa-memex-dark-web/
