Internet Deep webstore searching

Deep web store accessing - By sateesh kundam

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.

Although the Internet is the newest medium for information flows, it is the fastest growing new medium of all time, and becoming the information medium of first resort for its users. Note that the Web consists of the surface web (fixed web pages) and the deep web (the database driven websites that create web pages on demand).

Traditional search engines create their indices by spidering or crawling surface Web pages. To be discovered, the page must be static and linked to other pages. Traditional search engines cannot "see" or retrieve content in the deep Web - those pages do not exist until they are created dynamically as the result of a specific search. Because traditional search engine crawlers cannot probe beneath the surface, the deep Web has heretofore been hidden.

The deep Web is qualitatively different from the surface Web. Deep Web sources store their content in searchable databases that only produce results dynamically in response to a direct request. But a direct query is a "one at a time" laborious way to search. We should have search technology which automates the process of making dozens of direct queries simultaneously using multiple-thread technology which is capable of identifying, retrieving, qualifying, classifying, and organizing both "deep" and "surface" content. Clearly, simultaneous searching of multiple surface and deep Web sources is necessary when comprehensive information retrieval is needed.
