  <pre><code>&lt;f:form action="search" arguments="{keyword}"&gt;
    &lt;f:form.textfield name="keyword" value="Suchbegriff"&gt;
    &lt;f:form.submit value="Suchen" /&gt;
  &lt;/f:form&gt;
  </code></pre>
  
  <p>//added to <strong>ItemController.php</strong></p>
  
  <pre><code>/**
   * action search
   *
   * @param \string $keyword
   * @return void
   */
  public function searchAction($keyword='') {
  
      $items = $this-&gt;itemRepository-&gt;findKeyword($keyword);
      $this-&gt;view-&gt;assign('items', $items);
  }
  </code></pre>
