摘要

With the explosive increase of the network information,it is more and more difficult for people to look up information. The occurrence of the Web search engines overcomes this problem in some degree. However, because different search engines use different mechanisms, scope and algorithms, the repetition of the search results for the same query is no more than 34 %. If wish to get relativly fullscale ,accurate search results,multi-search engines should be used and the meta search engines occur. In this paper ,the meta search engines are surveyed. At first ,the history ,the principles and the elements of the meta search engines are discussed. Then,the related creteria of the meta search engines are analyzed and several typical meta search engines are compared. Finally,on this base,the trend of the meta search engine is introduced.
