How to sort products by seller in Woocomerce?

Question

WordPress

The site uses the WC Vendors plugin.
Due to the large number of goods, there was a need to sort goods by seller in the site admin panel.
The standard search does not search for items by seller. And the necessary filter is missing in the admin part of the site.
The plugin developer answered this question:

You will need to modify how the product search works in WooCommerce to include post_author and if you'd like to search by store name you'll have to include a user meta key search. This is not advised as meta searches are very slow.
