[Plugin: WooCommerce – excelling eCommerce] Woocommerce Product Search not searching product tags?

My client uses product tags on all her products and we have found that the product search widget doesn’t seem to be searching those.

For example, this listing (http://shop.dimpleprints.com/shop/fish-under-the-sea/) has the following tags: Animals, boy, Boys, crab, fish, girl, Girls, invite, Nautical, octopus, Pool, preppy, printable, turtle, under the sea, whale. But when I search “whale” or “pool” it returns no results. Am I missing something? Any way around this?

This feature is very important to their shop. Thanks!
