The Invisible Web (also known as the Deep Web Deepnet, Dark Web or the Hidden Web) refers to World Wide Web content that is not part of the surface Web, which is indexed by standard search engines. Accessing the Invisible Web is an important part of the repertoire of Investigative Research.
Techniques
Searching for filetypes
Many researchers search for PDF files by using the search limiter filetype:pdf. The search engine OSUN.org provides an interface for searching PDF, DOC and PPT files.
