Return metadata fields in Google Search Appliance result

I'm working with a Google Search Appliance machine using the feed type metadata-and-url.

I posted the feed to the GSA machine sucessfully, but when I do a search (using my appliance URL) to get the XML from the GSA machine, I cannot see the metadata in the returning XML. Should I use some querystring parameter?

Any idea?

This is the xml posted to the GSA machine:

<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE gsafeed PUBLIC "-//Google//DTD GSA Feeds//EN" "">
<gsafeed>
  <header>
    <datasource>TestXMLFeed</datasource>
    <feedtype>metadata-and-url</feedtype>
  </header>
  <group>
    <record url="http://www.WHATEVERURL" action="add" mimetype="text/html" lock="true">
      <metadata>
        <meta name="Creator" content="testcreator"/>
        <meta name="Project" content="testproject"/>
        <meta name="TypeOfContent" content="testtypeofcontent"/>
      </metadata>
    </record>
  </group>
</gsafeed>

This is what I get from the search:

<GSP VER="3.2">
     <TM>0.010752</TM>
     <Q>Test page</Q>
     <PARAM name="q" value="testpage" original_value="testpage"/>

Add the parameter &getfields=* to your google search appliance search url page.

And for filtering after on those metadata is necessary to add partialfields=Creator:testcreator in the querystring too.
