Hide products without Thumnails from search

Hi, I’m working on a site that uses the Advanced Woo Search plugin. And I’ve been able to hide from the store products that don’t have a thumbnail, since some are being imported by the clients inventory system that way.

I did it using this code:

add_action( 'woocommerce_product_query', 'hide_image_pre_get_posts_query' );
function hide_image_pre_get_posts_query( $query ) {
    $query->set( 'meta_query', array( array(
      'key' => '_thumbnail_id',
      'value' => '0',
     'compare' => '>'
   )));
}

But they still show up on the search bar, so I’m wondering if there’s a way to also hide them from appearing in any search.

Thanks in advance.
