I have often wished that our database could do that. In fact, just now, in the Year of Introduction text box I tried <1990, and also ≤1990, and also Bet 1990 AND 1980. None of the searches worked. I wish it could be set up to work with all of those types of numeric searches, in both the Year of registration, and the year of introduction.
@KentPfeiffer are you listening?
