Intranet搜索引擎设计与实现

摘要

随着企业内部网络应用的深入,Intranet内部的信息资源越来越庞大,怎样为这些数据信息构建索引是我们面临的主要任务,而全文检索的产生解决了这一问题.目前越来越多的中小企业采用Linux系统作为Web平台,并且利用检索系统来管理内部繁多的文本和HTML文件.文章对WWW搜索引擎的全文检索及其相关技术进行了分析和讨论,实现了一个基于Linux环境的Intranet搜索引擎LISE(Linux Intranet Search Engine).LISE利用了基于词表的索引方法,为用户提供了更加准确的信息,能满足多种中小企业用户的需求.%With the increasing depth of the network application within enterprise, the information resource in intranet become larger and larger. It is our main job that how to build index for masses of data. However, full-text retrieval is just for people to do this. Now more and more small or medium enterprise use Linux as its web platform, and they use retrieval system to manage their many documents and HTML files. This thesis analyze and discuss Full-text retrieval and its related technologies in WWW search engine in detail, and realize a search engine prototype-LISECLinux Intranet Search Engine), which based on Linux. LISE use indexing method based phrased list, it can provide more correct information for the users and meets the requirements in many kinds of enterprise users.
