Nutch Crawl does not working

Question

I want to crawl a site using Apache Nutch 1.12 and index the data into Apache Solr. I have followed this tutorial.

My seed.txt file has this url http://nutch.apache.org/

In my regex url filter I am having like this +^http://([a-z0-9]*.)*nutch.apache.org/

when I try to fetch the data i am getting only the url in my seed.txt file.
