摘　　要：相比较传统的集中式信息检索系统,基于P2P方式的信息检索系统具有成本低、可扩展性好、容错性强等优点,可充分挖掘网络边缘资源,并可提供个性化的信息服务。首先分析了传统信息检索存在的问题,指出P2P信息检索发展的动机,然后介绍了几种在P2P中存在的检索机制,描述了一般的体系框架,最后给出了基于jxta协议中的检索算法,并讨论了P2P信息检索遇到的一些问题和发展方向。Compared with the traditional centralized of information retrieval system, the information retrieval system based on P2P way is strongly fault- tolerant,good expansible,and cost less,can fully excavate the edge resources of the network,and can offer individualized information service. We firstly analyse that traditional information retrieval exists the questions. Secondly,we point out P2P motive of development of information retrieval. Thirdly, we introduce several kinds of search mechanisms existing in P2P network. Then we describe the general system frame,and provide the search algorithm in jxta agreement. Finally, we discuss some questions and developing direction that P2P information retrieval meets.
