摘要
本文比较详细地介绍了互联网搜索引擎的概念、发展历史、工作原理和未
来趋势。先从工作流程的角度解释了搜索引擎实现机制,通俗地概括为预处理和
提供查询服务,描绘了整个技术构成易于理解的概览图。接着对各个分支模块,
包括爬虫、分布式文件系统、索引和排序规则展开详细论述,然后以实践经验为
指导,分析了各个模块的改进设计。本文内容是以搜索引擎理论研究为主,并对
未来搜索引擎的智能化、个性化发展趋势做了详细的介绍。本文对于从事网络技
术开发、信息检索技术和数据挖掘研究都有一定的参考意义。

Abstract
In this paper, a more detailed introduction of the Internet search engine’s
development history, theory and technology was presented. Start with the perspective
of workflow explained the mechanism for implementing a web search engine, which
is summarized as pretreatment and web services. It can be divided as spider,
distributed file system, indexing and ranking rules. Further more, I put forward my
own opinion of ranking algorithm improvement. Meanwhile, I explained the search
engine architecture design principles and a comparative analysis of other possible
design options. Because of strict logical ratiocination and abundant experimental data,
it’s fit for variety of readers. And intelligent, personalized trend of search engine
development are described in detail. It is a good reference for Information Retrieval
and Data Mining research and web search engine development.
Key words
