I have answered by myself:
public static function search_format($id) {
if(!Utils_RecordBrowserCommon::get_access('task','browse')) return false;
$row = self::get_tasks(array('id'=>$id));
if(!$row) return false;
$row = array_pop($row);
return Utils_RecordBrowserCommon::record_link_open_tag('task', $row['id']).__( 'Task (attachment) #%d, %s', array($row['id'], $row['title'], $row['description'])).Utils_RecordBrowserCommon::record_link_close_tag();
}
Just add $row['description'] in the array of columns Epesi looks building query.
