Any example of product custom queries?

Hi, guys!

I noticed that following code (to get products with a price range using WP_Query) does not work as expected in latest version of woocommerce 3.8, basically it does not work at all:

$query['meta_query'][] = [
	'key' => '_price',
	'value' => [ absint( $min ), absint( $max ) ],
	'compare' => 'BETWEEN',
	'type' => 'NUMERIC'
];

please, do you have any examples, how can i do a custom query to filter products with min / max price, order by popularity, average rating, etc.

thank you in advance
