title: How to exclude fields in a SOLR query
body: <p>I have a SOLR query which should fetch all the fields I store, except one field.<br>
  Say I have <strong>20</strong> fields, do I need to hard code the <strong>19</strong> fields I want to fetch in the<br>
  <code>&amp;fl=[f],[f],[f],....[f]'</code><br>
  Or is there a way to do something similar to<br>
  <code>&amp;fl=*,![f]'</code>  </p>
  
  <p><code>[f]</code> stands for a field name.</p>
