摘　　要：基于元搜索引擎的跨库检索可以检索到通用搜索引擎检索不到的网络数据库资源,但必须解决元搜索引擎与数据库独立搜索引擎间通信的协议标准问题。本文对目前这方面主要的三种通信协议标准OpenSearch,SRU和MXG进行了比较研究,以便为基于元搜索引擎跨库检索研究的发展提供一些有益的参考。Metasearch engines--based cross--database search can retrieve the network database resources that cannot be retrieved by the common search engines, and the search protocot standard for the communication between the metasearch engines and the local search engines of databases must be resolved. This paper conducts a comparison research on the 3 main search protocol standards： OpenSearch, SRU and MXG, and hopes to provide some beneficial references for the development of cross--database search based on metasearch engines.
