一个小型搜索引擎的设计与实现
摘 要
随着互联网和宽带上网的普及，搜索引擎在中国异军突起，并日益渗透到人们的日常生活中，在互联网普及之前，人们查阅资料首先想到的是拥有大量书籍的资料的图书馆。但是今天很多人都会选择一种更方便、快捷、全面、准确的查阅方式--互联网。而帮助我们在整个互联网上快速地查找到目标信息的就是越来越被重视的搜索引擎。
本文通过分析国内外搜索引擎的发展现状，提出了一种功能强大，操作简单，通用性强，可以满足用户对信息搜索需要,利用asp技术实现的一个B/S体系结构的搜索引擎系统方案。文中着重论述了该系统的功能与实现、数据流程与存储、后台管理等。并对关键的有关技术作了较详细的介绍。论文在撰写过程中，力求将理论与系统应用相结合，对各种理论进行阐述的同时配合系统从实际应用和操作技巧上加以说明，希望能够更充分地体现到这些知识与技术在本系统中的应用与实现。

The Design and Implementation of a Small Search Engine
Abstract
With the popularization of the Internet and surfing the Net broadband search engine likes a dark horse in China, going to people's daily life day by day. Before this, when people consult materials the first thought is the library that has a large number of books. Now, more and more people will choose Internet to search for information. It's more convenient, and accurate for searching information. The search engine that helps us in the whole Internet to quickly identify target information is played more and more attention to.
Through analyzing the current development of search engine in domestic and international, this paper gives a plan that achieves the formidable function, simply operating, stronger versatility and satisfies the users to the information search need, and realizes a systematic scheme of search engine of B/S system structure with the technology of asp. This paper mainly describes the function and realization of this system, data procedure and storing, back-stage management, etc. And also introduces to the key relevant technology in detail. During this period, I've made a lot effort to union the theory and practice, and coordinates with system to explain from practical application and operation skill while explaining various kinds of theories, hope to more fully reflect the knowledge and application in this system of technology and realize.

系统是一个B/S结构的系统，采用IIS 5.0＋Microsoft Access＋asp作为开发环境。它的发布需要有Web服务器的支持，且需要数据库系统来对系统数据进行存储，查询，修改，删除，及时更新系统信息。系统设计6个功能模块，分别是网站搜索模块、图片搜索模块、分类目录模块、网站登录模块、网站管理模块和管理员登录模块。用户登录到首页，首先进入的是网站搜索界面。点击页面上其他功能模块的超链接，可进入相应的模块界面。网站登录模块和网站管理模块需要用户输入用户名和密码，成功通过验证才能进入相应的管理模块，如果验证失败则返回到前一个功能模块界面。管理员登录模块同样需要成功通过验证才能进入相应的管理模块。但他又提供了网站审核、网站管理和分类目录修改3个子模块。
