Search with attributes plugin

is there a plugin that let me search products in woocommerce by attributes?

on my website http://www.exclusive-chrono.com i have this search form where i want my customers to be able to enter for example 1975 and al the watches show up where the mannufactoring year 1975 is entered as an attribute. or where I can enter the productnumber and al the watches with that productnumber will be shown.

At the moment only the watches with this information in the product tittle show up.
