title: How do I change schema.xml without restarting Solr?
body: <p>I've added <code>"copyField source="product" dest="text"/"</code> in <strong>schema.xml</strong></p>
  
  <p><strong>solrconfig.xml</strong></p>
  
  <pre class="lang-xml prettyprint-override"><code>&lt;requestHandler name="/select" class="solr.SearchHandler"&gt;
    &lt;!-- default values for query parameters can be specified, these
         will be overridden by parameters in the request
    --&gt;
    &lt;lst name="defaults"&gt;
      &lt;str name="echoParams"&gt;explicit&lt;/str&gt;
      &lt;int name="rows"&gt;10&lt;/int&gt;
      &lt;str name="df"&gt;text&lt;/str&gt;
    &lt;/lst&gt;
  &lt;/requestHandler&gt;
  </code></pre>
  
  <p>I restarted solr and loaded the data again to reflect changes made. My question is whether it is necessary to restart solr every time I make a change in schema.xml. </p>
