searching catalog

Maybe its just a brain cell (or two has died). I am trying to do searches for various German beer tokens, German notgeld, various medals etc, things not commonly called coins. I attempt to change the search parameter to *token* or whatever the case may be but always results come up "no result". What am I missing?

Oh and forgot to mention, I can do a google search with "numista" and whatever parameter I am searching for, for example "beer token" and I get a list that pops up with links to various numista listings. So I know that at least some of what I am looking for is there already. I just havent been able to get the numista search engine to bring anything up.
