<records interface="plone.app.querystring.interfaces.iqueryfield"        prefix="plone.app.querystring.field.course"> <value key="title">course</value> <value key="description">a custom course index</value> <value key="enabled">true</value> <value key="sortable">false</value> <value key="operations">     <element>plone.app.querystring.operation.string.is</element> </value> <value key="group">metadata</value> </records>
