I tried it, and it turns out that it is necessary to leave a space before the minus sign. Also, the parentheses method works better. I don't know why, but if you just list "t206 -rp-reprint-topps" the search engine still provides plenty of the offending reprints. But, if you use t206 -(rp,reprint,topps,2009), you're going to have the same good time you had five years ago.
I thought David made a good point about how this procedure will also exclude items whose descriptions contain the words "not a reprint." But maybe it's a fair price to pay for a reprint-free and topps-free experience. The happy hunting might just be worth it!!!

Not quite the same as an algebraic equation. (Actually, it works on Boolean algebra)
When you do a search and list the criteria, without parentheses, such as
SEARCH: 1 2 -3 -4 (where 1, 2, 3, and 4 are search criteria)
it reads each space as an "AND" thereby looking for search criterion 1 AND search criterion 2 AND not (if a minus sign is used) search criterion 3 AND not seach criterion 4
When items are placed in parentheses it is the equivalent of saying OR.
SEARCH: 1 2 -(3,4)
is read as search criterion 1 AND search criterion 2 AND not (if a minus sign is used) search criteria 3 OR 4.
Only one of the "OR" criteria need be present to exclude the listing from the search. This is an important differentiation you are trying misspelling variations like (topp,topps,top) for a positive search and not elimination.
