title: Is it possible to get the keywords in the documents returned by Solr
body: <p>Solr provides an easy way to search documents based on keywords, but I was wondering if it had the ability to return the keywords themselves? </p>
  
  <p>For example, I may want to search for all documents created by Joe Blogs last week and then get a feel for the contents of those documents by the keywords inside them. Or do I have to work out the key words myself and save them in a field?</p>
