How to filter woocommerce products by attachment of taxonomies/attributes to them

This feature is hidden to avoid confusing, just look on the screen below:

Filters tab: the logic drop-down of an attribute open with OR, AND, NOT IN, NOT EXISTS and EXISTS

For such filtration there is no necessary select terms as it filter by taxonomy/attribute attachment to the product generally, and not for terms. So if you understood and you need it: in your current wp theme functions.php file drop next code:

add_filter('woobe_filter_taxonomies_exists_show', function() {
    return true;
});

Refresh WOOBE manage panel page and special options will be appeared for taxonomies and attributes of tab Filters. Now you can filter products on belonging (or not belonging) to a particular taxonomy/attributes and make bulk edit to them.
