The Invisible Web (also called Deepnet , the Deep Web , Undernet , or the hidden Web ) refers to World Wide Web content that is not part of the Surface Web , which is indexable by standard search engines . It should not be confused with the dark Internet , the computers that can no longer be reached via Internet, or with the distributed filesharing network Darknet , which could be classified as a smaller part of the Deep Web. Mike Bergman , founder of BrightPlanet, [ 1 ] credited with coining the phrase, [ 2 ] has said that searching on the Internet today can be compared to dragging a net across the surface of the ocean: a great deal may be caught in the net, but there is a wealth of information that is deep and therefore missed.
Deep Web - Wikipedia, the free encyclopedia
There are several categories of search engine software: Web search or full-text search (example: Lucene ), database or structured data search (example: Dieselpoint ), and mixed or enterprise search (example: Google Search Appliance ). The largest web search engines such as Google and Yahoo! utilize tens or hundreds of thousands of computers to process billions of web pages and return results for thousands of searches per second [ citation needed ] .
