title: Solr - Adding custom 'non-multivalued' metatags
body: <p>I would want to add custom metatags for each of my page to determine its category, where I can do grouping by later on during search.</p>
  
  <p>Hence in my 'schema.xml', here is my definition of my metatag:</p>
  
  <pre><code>&lt;field name="metatag.description" type="text_general" stored="true" indexed="true" multiValued="false"/&gt;
  </code></pre>
  
  <p>However, value stored is still multivalued hence cannot be grouped.
  Tried restarting Solr to no avail. Any help is appreciated. Thanks.</p>
