摘　　要：随着校园网网页数量的不断增长,校园网搜索引擎应运而生。校园网搜索引擎系统的性能很大程度上取决于网络搜索器的性能,采集网页的速度是网络搜索器的1个重要指标。为了提高采集网页的速度,本文设计实现了1个多线程搜索器,并对内蒙古工业大学校园网进行了测试。实验表明,多线程搜索器可以把采集网页的速度从单线程0.9页/s提高到6.9页/s,采集网页的速度提高了7倍多。由此说明,采用多线程设计搜索器对提高搜索器采集网页的速度是很明显的。Campus network search engine,which is a new kind of search engine,has a great development with the growing of web pages come from campus network.The performance of it is depended on the function of the net hunter to a large extent and the speed of page acquisition is a principal merit to it.In order to accelerate the speed of page acquisition,the paper design and implement a multi-threaded search engine.The speed of page acquisition can be enhanced from 0.9 pages per second,up to 6.9 pages per second via the experiment test by the environment of IMUT campus network,which improves more than 7 times.It is obviously shows that the search engine designed by multi-threaded has an important effect on page acquisition.
