It still seems as though the descriptive words used in tags are open to interpretation.
"1966 Red Chevy" could be descriptive if the whole term is "1966 Red Chevy Truck."
"Hammered silver" could be descriptive as it usually means silver that has been hammered.
All in all, tags do not matter as much as the listing title per this Admin Announcement:

2. Titles - As we mentioned, we are giving more weight to titles. You should have descriptive titles for all your items and use words you think people will search for when looking for your item. As an example, if you think people will best find your item if you have “SALE 15% Off” in the title, put it first otherwise, make sure to list the most important things about your item at the beginning of the title.
3. Tags - There were a variety of issues raised by tags. Unlike titles, the order of the tags does not impact ranking. As always we encourage you to use tags that are relative and related to your item. You asked whether single word tags are given preference over multi-word tags. Single word tags do not necessarily perform better for all searches. We encourage you to use Shop Stats to understand which tags work better for your items.
