摘　　要：针对企业文档信息资源丰富而又缺乏有效搜索工具的问题,提出构建企业级搜索引擎。首先分析企业级搜索引擎应具有的功能和总体架构,在实现中,对Lucene索引器进行深入研究;在抓取器的体系设计中,采用插件设计思想,来对不同的文档类型解析、抽取;在任务调度方面,实现一套多任务并行的调度机制;在用户接口设计上,采用Yu i-ext组件和DWR远程对象调用框架,实现W eb方式下的异步通信,提升用户体验。The enterprise- level search engine is proposed to solve the problem that enterprise have abundant document information resources but lack of effective search tools. The function and the overall framework of the enterprise - level search engine are analyzed firstly. Lucene indexer is studied in depth during implementation secondly. Then the plug - in unit is used to carry out the analysis and extraction of different types of documentsi in design. A set of parallel multi -task scheduling mechanism is established in the task scheduling. When the user interface is designed,Yui - ext components and DWR remote object invocation framework is applied to implement asynchronous communication by the Web, which can promote the users＇ experience.
