title: Solr 'join' using text fields (from another collection)
body: <p>For a quick project (not homework, I promise!), I have a simple solr installation with two cores, 'people' and 'jobs'.  Each has some structured data, but also a text field.</p>
  
  <p>I'd like to do a query using people.text to query into jobs.text.</p>
  
  <p>I've not been able to find an example of this and the SolrQuerySyntax page doesn't reference collections or cores.</p>
  
  <p>There is no field for using a real 'join'.</p>
  
  <p>Is it possible?  Can you point me to an example/tutorial?</p>
  
  <p>Thanks.</p>
