title: How is the XML syntax for adding a multi value field to a SOLR 3 Server
body: <p>I guess this is an easy question but I seem to be unable to find it in the documentation or the Solr wiki. </p>
  
  <p>So, I just need to know how the syntax for adding a multi value field (arr) is.</p>
  
  <p>I know you can add any other field like</p>
  
  <pre><code>&lt;add&gt;
   &lt;doc&gt;
    &lt;field name="fieldname"&gt;fieldvalue&lt;/field&gt;
   &lt;/doc&gt;
  &lt;/add&gt;
  </code></pre>
  
  <p>Thanks.</p>
