城市公交专题搜索引擎的实现

The Implementation of Feature Search Engine for City Bus System

该文从搜索引擎技术开始,全面研究了专题搜索引擎的基本原理和相关技术,并设计实现了针对城市公交系统的专题性搜索引擎,该搜索引擎主要以Heritrix爬虫框架为后台支撑,利用Lucene软件进行文本索引,最后将搜索获取的因特网信息放入Excel表中,同时利用设计的客户端程序为用户提供关键词搜索功能;最后,阐述了设计过程中为提高专题性搜索功能所设计的几种核心方法。

Beginning with the search engines,this article develops the further study of the basic principle and related technology about feature search engines.And the article develops a feature search engine for city bus system.It uses Heritrix framework as search robot and Lucene as tools to indexing text.Finally it puts all information inside the Excel table.The client interface provides the function of searching Key words.At the end,it discusses four core technologies about improving the utility of this feature search engine.
