To improve the correct-rate and completeness-rate of search,a topic-specific meta-search engine is designed.A bogus crawler is invented,which collects information by the normal search engines,so that the search-area is wider than the normal search engine.The feedback mechanism is adopted and the search-history of user is considered,which make the search result is more imminent to the purpose of the user.Owing to the strategy of topic-specific and mending the arithmetic of similitude-degree of the texts,the correct-rate is improved.Both the correct-rate and completeness-rate of searching are improved,the response time is decreased as well,at the same time,the request of capability of the server is reduced.
