body: <p>I am using Nutch-1.8 for crawling website and solr for indexing.i need to crawl entire website till the last child link without specifying depth parameter(-depth)</p>
  
  <p>this is the command i am using to crawl and index urls</p>
  
  <p><strong>command :</strong> bin/crawl seeds brainiademo <a href="http://localhost:8983/solr/" rel="nofollow">http://localhost:8983/solr/</a> 10</p>
  
  <p><strong>syntax</strong> : <code>bin/nutch crawl &lt;urlDir&gt; [-solr &lt;solrURL&gt;] [-dir d] [-threads n] [-depth i] [-topN N]</code></p>
