摘要
网络信息检索工具是Ｉｎｔｅｒｎｅｔ信息资源快速定位的重要方法。文章中结合建立Ｉｎｔｅｒｎｅｔ化学信息资源导航系统ＣｈＩＮ（ＣｈｅｍｉｃａｌＩｎｆｏｒｍａｔｉｏｎＮｅｔｗｏｒｋ）网页全文检索系统的要求，讨论了全文检索的产生、现状和发展趋势。在对信息搜索机制和主要全文检索软件的分析比较的基础上，采用全文检索软件Ｉｓｅａｒｃｈ开发了ＣｈＩＮ网页的全文检索系统，同时给出了ＣｈＩＮ网页全文检索系统的应用实例。
Web Search Engine is an fast and primary tool for locating special information among huge amount of information resources on Internet. The status and development of the Web search engine are discussed in this paper, through the case of development of full text retrieval system for ChIN (Chemical Information Network) Web pages. The full text retrieval software Isearch is employed in the full text retrieval system for ChIN, based on the analysis of the search mechanics and the comparison of some search engine softwares. A case study of development of the full text retrieval system for ChIN is given in this paper.
