invisible web, hidden web, and deep web all refer to the same thing: a massive storehouse of online data that the search engines don't capture. That's because terabytes of information are buried in databases and other research resources. Searchable and accessible online but often ignored by conventional search engines, these resources exist by the thousands. Known in research circles as the invisible, deep, or hidden Web, this buried content is an estimated 500 times larger than the surface Web, which is estimated at over four billion pages. This mass of information represents a potent research resource, no matter what your discipline or interest. Below are some tools to help you mine it. Students and serious researchers may also find our collections of web directories and scholarly and academic research tools and strategies useful.
Searchwiki or Swicki's purpose is to bridge the gap between searchers and relevant results. As the web grows and evolves, web search needs to grow and evolve too. Searchwiki technology improves on existing general web search by enabling vertical, community site and web searches to be initiated from any website. A searchwiki's strength is in its community appeal and dynamic social search cloud. As such, collaboration between groups of people with similar interests using a Searchwiki will quickly produce much more relevant and tailored results for a common group than a generic search engine would.
