According to the project requirement, I prefer to use Heritrix because of the following

  • claw all contents in website
  • easier to extend based on the project

2) Lucene+Heritrix开发自己的搜索引擎  http://virgoooos.iteye.com/blog/185850

Heritrix是IA的开放源代码,可扩展的,基于整个Web的,归档网络爬虫工程
Heritrix工程始于2003年初,IA的目的是开发一个特殊的爬虫,对网上的
资源进行归档,建立网络数字图书馆,在过去的6年里,IA已经建立了400TB的数据。
IA期望他们的crawler包含以下几种:
宽带爬虫:能够以更高的带宽去站点爬。
主题爬虫:集中于被选择的问题。
持续爬虫:不仅仅爬更当前的网页还负责爬日后更新的网页。
实验爬虫:对爬虫技术进行实验,以决定该爬什么,以及对不同协议的爬虫爬行结果进行分析的。
Heritrix的主页是http://crawler.archive.org
