A real
implementation from this project is whether the ability of testing on general
search engine can be applied on testing deep web search engine. The general
search engines such as Google and Yahoo have been widely approved in their
proper results and links. However, many sites may not allow their documents to
be indexed but instead may allow the documents to be accessed through their
search engines only, these sites are part of the so-called Deep Web [1][17].
The deep web search engines which only focus on their own data base and pages,
data or documents which are kept privately and cannot be searched by general
search engines. Take www.taobao.com as an
example, it is a online commercial trading site like www.ebay.com, Taobao apparently abandons
general search engines such as www.baidu.com
and www.google.com to access its
commodities results after the negotiations broken with the big search engine
companies. This leads people who want commodity and price information have to
go directly to Taobao’s own search engine interface and browse result items in
Taobao’s website. Obviously, search engines in Taobao are probably developed by
their own or contract consultant software teams, the performance then will be
an interesting topic rather than the ones generally accepted by the public such
as Google and Yahoo. The specific introduction for deep web and implementation
of deep web search engines are not part of this project, but the practical
value from this project can offer a feasible way in testing local and small
search engines embedded in their own web sites.
