摘　　要：现有的Internet网站中一些大的搜索引擎,其功能很全,正因其功能强大,则难免在细节上出现一些不太完善的地方,如对搜索结果的链接没有实现有效性检测,导致了在网页中搜索结果出现了许多无效链接。针对这一缺点,本文先给出了元搜索引擎的定义、元搜索引擎的原理及搜索引擎与元搜索引擎的主要区别,同时还指出了搜索引擎的不足,最后提出了一个搜索引擎改进方法,给出了思路流程与方案解析,即在客户端实现过滤,这样既可以保持搜索的快速性,又能达到过滤链接的效果,并用UML时序图描述了搜索引擎的检索结果,同时进行有效性检查,建立这样的元搜索构想功能即是对如上搜索得到的网址进行检测过滤,以提示或去除其中无效的链接,使用户能够更加准确、快捷地获取所需要的资料信息。Now some big search engines＇function in internet are as clear as a bell, but they are hard to avoid not being perfect in their details, such as they can check the links＇validity in the search result, and lead to appear a lot of error links In web page, and lower the search efficiency on a certain degree, so they bring the inconvenience to customers. In view of this weakness, the definition of metasearch, the principle of meta-search and the difference between search engine and meta-search engine are provided. Meanwhile, the weakness of search engines is referred in the paper. Finally, a search engine upswing method and the thought flow and scheme resolution are also given in the paper. That is to be filtrated in the client server. So it can not only keep rapidity of search, but also reach the effect of filtrating link, and decribe search result of search engine with UML time sequencing graph, and make the efficient check. The function of the meta-search which we have thought to build is to check or filtrate the links in the search result, to hint or delete these invalid links, and make the customers obtain the information accurately and fast.
