摘　　要：元搜索引擎是搜索引擎之上的搜索引擎。用户递交检索请求,元搜索引擎接收该请求后,把它提交给多个预先选定的搜索引擎成员,集中所有的查询结果并以统一的格式返回给用户。首先概述了元搜索引擎的原理和现状,分析了当前研究元搜索引擎的难点所在,并提出改进方案。在此基础上,设计了元搜索引擎的总体框架,提出了查询代理、搜索代理、运算代理三大功能模块,并阐述各代理的功能流程。Meta-search engine is the set of commercial search engines. It takes the request from the user and sends it to the member search engines. And retrieved results got from different search engines are integrated into one unified format and presented to the users. The principles and actuality of the metasearch engine are discussed. The difficulties of making the meta-search engines more power are pointed out. Based on this discussion, we draw up some methods for improving the performance of it. The framework is designed, which includes three modules： enquiry agent, search agent and operation agent.
