I want to tag a product with information outside of the description which wouldn't be displayed. This is applicable for an auto parts website that would have a year/make/model dropdown search.
So for example, a product has the title "2004-07 Honda Civic Headlights", the product would have tags 2004, 2005, 2006, 2007, Honda, and Civic so I can create a search on these tags.
Is there an existing field I can use? I looked at attributes, but it doesn't seem appropriate.
