Relevanssi and Blog Tags

Hi,
I implemented the Relevanssi Search plugin.
Since then the tag links in the sidebar tag cloud don’t give any results anymore.

I’ve implemented Relvanssi in the functions.php:

add_filter('avf_ajax_search_function', 'avia_init_relevanssi', 10, 4);
function avia_init_relevanssi($function_name, $search_query, $search_parameters, $defaults)
{
	$function_name = 'avia_relevanssi_search';
	return $function_name;
}

function avia_relevanssi_search($search_query, $search_parameters, $defaults)
{
	global $query;
	$tempquery = $query;
	if(empty($tempquery)) $tempquery = new WP_Query();

	$tempquery->query_vars = $search_parameters;
	relevanssi_do_query($tempquery);
	$posts = $tempquery->posts;

	return $posts;
}
