随着Internet的迅速发展，校园网也不断发展，校园网中的信息量不断增大，我们在查找信息时也因其信息资源量大而不能很快找到所需的信息，所以一种基于校园网的搜索引擎也就应运而生了。而网络蜘蛛技术是搜索引擎的关键。本文围绕这一技术而展开。首先从搜索引擎的种类和原理整体分析了搜索引擎，然后研究网络蜘蛛这一技术，从网络蜘蛛技术的原理、一般系统结构、关键技术、技术实现等几个方面来分别分析、为设计校园搜索引擎作最基本的工作。选择.NET为设计平台，以C#语言编写程序。-With the rapid development of Internet and campus network will also be continuous development of campus network increasing the amount of information, we have information when they search for their large amount of information resources and can not quickly find the required information, so based on the campus network came into being a search engine it. And network spider technology is the key to search engine. In this paper, and start focusing on this technology. First, from the search engine types and principles of the overall analysis of the search engine spiders then research network of the technology, from the network spider technology principle, the general system structure, key technologies, technologies to realize several aspects such as analysis, respectively, for the design of the campus search engine for the most basic work. Choice. NET platform for the design to C# programming language.
