Support Grouped Products

Hi,

First of all, great and intuitive plugin. Thank you! I am wondering if there’s any possibility of the filtering supporting grouped products?

Let me explain:
1. I have 10 simple products
2. I have 1 grouped products grouping all of the above simple products
3. When I search for e.g. a custom taxonomy, the plugin only returns the simple product and not the grouped product.
