Set nopaging for non-logged in users

Dear team,

I am trying to set up a restriction to show only 3 posts in the search result page for non-logged in users through the code below.

add_filter( 'relevanssi_modify_wp_query', 'rlv_adjust_search' );
function rlv_adjust_search( $query ) {
	if ( is_user_logged_in() ) {
		return $query;
	}
	if ( $query->is_search() && !is_admin() && !is_user_logged_in() ) {
		$query->set( 'nopaging', true );
		$query->set( 'posts_per_page', 3 );
		$query->set( 'no_found_rows', true );
	}
	return $query;
}

It successfully restricted the number of posts. However, the pagination cannot be disabled. I checked the documentation in the website but still cannot find the solution.

Do you happen to have any idea about how to disable the pagination for non-logged in users?

Thank you for your reply in advance.

Best regards,

Lin
