Search by variable product name

Hi, I’m am using your plugin on two websites and I like it. However, I would like to be able to search products also by the title of the products variations
For example I have paints cans of several types (let’s say “Base”, “Spray”, “contrast” which are the variable products) that have each severeal colors (which are the variations names)
So I want to find the “red” variations products of Spray, Contrast and Base when I type “red” in the search bar. Because for the moment when I type “red” it is showing nothing since is is not the title of the variable product, but the title of one of the variations.
Thank you in advance for your help. Maybe it is in the premium version of the plugin ?
