Merge 2 WP_Query()

Merge wp_query

<?php

$query1 = new WP_Query($arg1);
$query2 = new WP_Query($arg2);
        
$query = new WP_Query();

$query->posts = array_merge( $query1->posts, $query2->posts );

// we also need to set post count correctly so as to enable the looping
$query->post_count = count( $query->posts );

?>

Thanks for your snippets. The 11th line of code is very important!!!!

guys, How to display the data ? like title, custom post, etc ?

I try, $query->title(); is not working ...
