Relevanssi Search not showing results on the search Page

Hi Kriesi Team,
i use the plugin Relevanssi for search. i use this function snippet and put it at the bottom of the file:

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;
}
