[Plugin: WooCommerce] Searching multiple products

Hi there!
I’m looking for a plugin or a code alteration that would allow me to search for multiple products with the WooCommerce search widget.

As of now, I have a few products (Sign One, Sign Two, Sign Three, etc.). If I search “One Two” in the search bar, no results appear. I would like bother Sign One and Sign Two to result, because they both contain a queried term. As of now, the search is an AND query, rather than OR. If that makes sense.

How can I alter the search function, or even another plugin, so that I can search for products in the manner I am describing? I already have the “Search for tags” plugin, which has been great. I would prefer not to add the product name as a tag- I have already considered that workaround. Any other possibilities? Thanks!
