Search engines for deep web

Deep Web

The Deep Web (also called the Deepnet, the Invisible Web, the Undernet or the hidden Web) is World Wide Web content that is not part of the Surface Web, which is indexed by standard search engines. It represents a gargantuan part of the internet which is not accessible through regular searches via google or other search engines.

Searching on the Internet today can be compared to dragging a net across the surface of the ocean. While a great deal may be caught in the net, there is still a wealth of information that is deep, and therefore, missed. The reason is simple: Most of the Web’s information is buried far down on dynamically generated sites, and standard search engines never find it.

So How do we access or search info from deep web? Well there are few special search engines available which can give you some glimps of it, I would list a few of them below:

  • Complete planet - General purpose for dynamic databases
  • WWW virtual library - The oldest catalog on the web! by Tim Berners-Lee, the creator of the web
  • Infomine - Built by a pool of libraries in US, mostly academic purpose
  • InfoPlease - For encyclopedias, atlas, biographies etc
  • DeepPeep - Mostly for fetching databases and web services info
  • IncyWincy - It’s a serching for search engines meta-data Closed
  • DeepWeb - Covers Science, Medicine and Business and have 5 sub-search engines
  • Scirus - More inclined toward scientific info
  • TechXtra - Mostly for mathematics and computing needs
