Does solr do web crawling?

solr, web-crawler

Solution

Solr 5+ DOES in fact now do web crawling! http://lucene.apache.org/solr/

Older Solr versions do not do web crawling alone, as historically it's a search server that provides full text search capabilities. It builds on top of Lucene.

If you need to crawl web pages using another Solr project then you have a number of options including:

- Nutch - http://lucene.apache.org/nutch/

- Websphinx - http://www.cs.cmu.edu/~rcm/websphinx/

- JSpider - http://j-spider.sourceforge.net/

- Heritrix - http://crawler.archive.org/

If you want to make use of the search facilities provided by Lucene or SOLR you'll need to build indexes from the web crawl results.

Problem

I am interested to do web crawling. I was looking at `solr`. Does `solr` do web crawling, or what are the steps to do web crawling?
