[‘operator’] = ‘or’; outsite searchpage (Similar)

Hi,

i use Relevansi outside of the searchpage to get similar content. First i use this snippet:

$query = new WP_Query();
$similar = get_transient('relevanssi_similar_' . $post->ID);
if (empty($similar)) {
	$query->query_vars['s'] = $post->post_title;
	$query->query_vars['posts_per_page'] = 6;
	$query->query_vars['operator'] = 'or';
	relevanssi_do_query($query);
	//$similar = "<ul>";
	$similar = "";
	foreach ($query->posts as $r_post) {
		if ($r_post->ID == $post->ID) continue;
		$link = get_permalink($r_post->ID);
		$title = get_the_title($r_post->ID);
		$similar .= '<li class="list-group-item"><a href="'.$link.'" title="'.$title.'" >'.$title.'</a></li>';
	}
	//$similar .= "</ul>";
	set_transient('relevanssi_similar_' . $post->ID, $similar, 60 * 60 * 24 * 4);
}
echo $similar;

But partly it comes before the some entries from the internal search not appear in the similar articles.
Therefore, I hollow the entry using the following code:

$query = new WP_Query();
$query->query_vars['s'] = $post->post_title;
$query->query_vars['posts_per_page'] = 6;
$query->query_vars['paged'] = 1;
$query->query_vars['operator'] = 'or';
relevanssi_do_query($query);
	$similar = "";
	foreach ($query->posts as $r_post) {
		if ($r_post->ID == $post->ID) continue;
		$link = get_permalink($r_post->ID);
		$title = get_the_title($r_post->ID);
		$similar .= '<li class="list-group-item"><a href='.$link.'  title="'.$title.'" >'.$title.'</a></li>';
	}
	//$similar .= "</ul>";
	
	echo $similar;

Unfortunately the code $query->query_vars['operator'] = 'or'; does not work here.
