How to search for many post types?

Question

I actually wanted to reply to another post, unfortunately that is no longer possible.

Therefore a short and crisp question. ;-)

If I want to search in several post types, can I simply work with 'post_type' => 'post' with comma values?

'post_type' => 'post', 'Pages', 'etc ..'

This is documented here: https://developer.wordpress.org/reference/classes/wp_query/#post-type-parameters

So to search for several post types you do:

$args = array(
    'post_type' => array( 'post', 'page', 'movie', 'book' )
);
$query = new WP_Query( $args );
