title: nutch and solr for multiple Domain
body: <p>I want to create custom search engine for multiple domain.<br>
  How can I use solr with nutch to create a custom search for 500+ domains, while searching each domain should be able to show its own data.</p>
  
  <p>e.g.<br>
   example.com exapmle2.com example3.com and so on, When ever user searches on example.com he should get data which belongs to example.com same for example2.com and so on  </p>
  
  <p>these website may be blog post, e-commerce site, classified site or hotel reservation site. </p>
  
  <p>any suggestion would be appreciated.  </p>
