Is there a way to display the description meta tag text in the search results for a Webvanta site page?

I've tried the following in a <w:each search="true"> loop:

        <w:if_item type="webvanta_page_type">
          <p><a href='<w:path url="default"/>'><w:name /></a><br />
          <w:meta:description tag="false" /></p>
        </w:if_item>
