Variable products search
Plugin works not only with simple WooCommerce products, but with variable products as well.
Variable products are a product type in WooCommerce that lets you offer a set of variations on a product. For example different t-shirt colors or sizes can be set as product variations.
You can read how to create product variations here.
There is no need for some extra work in order to make variable products work with search plugin. When you create a variable product and save it, it will already be in the plugin index table and can be displayed in search results.
That's how variable products look in search results:
