摘要

网络中的资源非常丰富，但是如何有效的搜索信息却是一件困难的事情。建立搜索引擎就是解决这个问题的最好方法。本文首先详细介绍了基于英特网的搜索引擎的系统结构，然后从网络机器人、索引引擎、Web服务器三个方面进行详细的说明。为了更加深刻的理解这种技术，本文还亲自实现了一个自己的搜索引擎——新闻搜索引擎。

新闻搜索引擎是从指定的Web页面中按照超连接进行解析、搜索，并把搜索到的每条新闻进行索引后加入数据库。然后通过Web服务器接受客户端请求后从索引数据库中搜索出所匹配的新闻。

本人在介绍搜索引擎的章节中除了详细的阐述技术核心外还结合了新闻搜索引擎的实现代码来说明，图文并茂、易于理解。

Abstract

The resources in the internet are abundant, but it is a difficult job to search some useful information. So a search engine is the best method to solve this problem. This article fist introduces the system structure of search engine based on the internet in detail, then gives a minute explanation form Spider search, engine and web server. In order to understand the technology more deeply, I have programmed a news search engine by myself.

The news search engine is explained and searched according to hyperlink from a appointed web page, then indexs every searched information and adds it to the index database. Then after receiving the customers' requests from the web server, it soon searchs the right news form the index engine,

In the chapter of introducing search engine, it is not only elaborate the core technology, but also combine with the modern code,pictures included, easy to understand.
