Introduction

Apache Nutch is an open source Web crawler written in Java. By using it, we can find Web page hyperlinks in an automated manner, reduce lots of maintenance work, for example checking broken links, and create a copy of all the visited pages for searching over. That’s where Apache Solr comes in. Solr is an open source full text search framework, with Solr we can search the visited pages from Nutch. Luckily, integration between Nutch and Solr is pretty straightforward as explained below.

Apache Nutch supports Solr out-the-box, greatly simplifying Nutch-Solr integration. It also removes the legacy dependence upon both Apache Tomcat for running the old Nutch Web Application and upon Apache Lucene for indexing. Just download a binary release from here .

???? Apache Nutch 是一個用JAVA語言編寫的開源web爬蟲項(xiàng)目。通過使用它，我們能夠以一種自動化的方式找到web頁面上的超鏈接，減少了大量的維護(hù)工作,例如檢查無用的鏈接或者創(chuàng)建一個所有訪問過搜索頁面的副本。講到這里Apache Solr出現(xiàn)，Solr是一個開源的全文檢索框架，通過solr我們能搜索Nutch訪問過的頁面。幸運(yùn)的是，整合Nutch和Solr是十分簡單的,例如下面的講解。

???? Apache Nutch 支持Solr拆箱即用，使得Nutch 和solr的整合非常簡單。同時也去除了遺留的依賴問題：不必在Apchce tomcat上運(yùn)行老版本的Nutch web應(yīng)用程序,也不必基于Lucene進(jìn)行搜索。請下載一個Nutch的二進(jìn)制版本從 http://www.apache.org/dyn/closer.cgi/nutch/
