It’s very big; the 60 largest Deep Web sources contain 84 billion pages of content. That’s about 750 terabytes of information — sufficient by themselves to exceed the size of the surface Web by 40 times. For comparison, Yahoo! (the largest Crawler-based search engine) indexes about 18 billion pages. Currently, BrightPlanet software is configured to query 70,000+ Deep Web sources. This number continues to grow.
