title: SOLR facet result as csv
body: <p>I have a collection in SOLR named <strong>sample</strong>, and I am trying to do some grouping on the collection by 
  running the below query</p>
  
  <pre><code>http://127.0.0.1:8983/solr/sample/select?q=*%3A*&amp;wt=json&amp;indent=true&amp;facet=true&amp;facet.pivot=Key1,Key2
  </code></pre>
  
  <p>This gives me correct result, with facet_counts after the search result.</p>
  
  <p>But what I would like to have is the facet result in a <code>.csv</code> format. I tried setting <code>wt=csv</code> but that gives me only the search result in csv, not the facet part.</p>
  
  <p>Is there any way to get the facet result also in csv format?</p>
  
  <p>Thanks</p>
