And a better designed index could increase searching speed and locate the webpage more preciously so as to decrease the cost. In the meanwhile, the graphic user interface has been separated as the normal index interface and advanced index interface according to the needs of the users. The format and content of output The outputs of the results are different among search engines, however, there are almost three parts: Criterion of Evaluating the Search Engine InLancaster and Fayen listed 6 factors to evaluate the search engines, coverage, recall ratio, precision ratio, response time, user effort, and format output Lancaster and Fayen, However, Scholarly essay search engine of ranking algorithms are based on the static feature of the text rather than language structure, which means the ranking algorithms would consider more about the number of words appearing than whether the word is a noun or adjective.
