摘 要

作为从浩瀚的网络信息资源中获取有价值的知识的一种有效技术，搜索引擎技术正悄然兴起，备受关注。经过几年的发展和探索，越来越贴近人们的需求，搜索引擎的技术也得到了很大的发展，如今搜索引擎已经是互联网应用中最重要的部分之一。

本文首先介绍了聚焦搜索引擎的研究背景和现状，设计了一个可根据用户需求从网上查询到有价值的信息的搜索引擎模型，再而介绍此次开发的互联网搜索引擎的运行环境及语言等与之关联的相关技术，着重分析了此搜索引擎查询系统的设计、分析和实现情况，主要包括页面的天气查询和新闻分类和用户普通查询方面等内容，并对实现各个功能的模块的技术进行了研究探讨。

本系统基于浏览器/服务器（Browse/Server）结构，使用Java作为开发语言，Myeclipse8.0作为开发工具，MySQL作为数据库，并在Tomcat 7.0上进行发布。由于JAVA语言具有可移植、安全性、解释执行、高性能、动态性，以及稍做修改后就具有跨平台性的优点，使得本系统操作方便、快捷。

ABSTRACT

As an effective technology to discover potential and valuable knowledge from the vast Web information resources, search engine technology is quietly rising, concern. After several years of development and exploration, more and more close to people's needs, the search engine technology has also been a great development, now the search engine has been Internet applications is an indispensable part of.

In this paper, we first introduce the research background and the present situation of search engine, design a according to the needs of the users from the Internet to query the data models of search engine, and then introduce the related technology of associated with the development of the Internet search engine, the running environment and language, focuses on the analysis of the search engine to obtain the technical principle of the foreground user demand and the backstage database interaction, and the technical realization of each function module are discussed.

The system based on Browser / server structure using Java as the development language, MyEclipse 2013 as development tools, MySQL as the database, and in the Tomcat 7.0 on the post. Because JAVA language has portability, security, interpretation, performance, high performance, dynamic, and slightly modified after the advantages of cross platform, making this system easy and fast operation.
