I know the saga of changing titles, tags, etc. to become more relevant, but I've done all that and I've also noticed that people selling similar jewelry have titles and tags that I would never think of searching, so by all means make your boxes more relevant - can't hurt, but don't expect a great upswing if you do. There does not appear to be any rhyme or reason to why an item comes up in a search. I have had items come up in searches that have nothing to do with my tags, titles, description and I can't imagine what triggered their appearance.
Good Luck with the holiday season and big sales for everyone no matter what search results your items appear in.
