Wordpress WooCommerce filter by attribute part?

Question

WordPress

There is an attribute containing something like the following:
18% viscose, 80% polyester, 2% elastan
20% wool, 70% rayon, 10% lycra It is
necessary that the filter can filter by words, respectively:
viscose, polyester, elastan, wool, rayon, lycra.
In other words, it gave out goods in the attribute of which, for example, contains "wool".
Choate searched all possible plugins and did not find how to set it up. I really don't want to introduce a new attribute and edit all the products.

Answer 1

I don’t know about attributes, but the WOOF plugin does filtering by part of the article (_sku)
