Date wildcard

Hi, is it possible to use a wildcard for the date field when doing an advanced search. If I have a coin where I can only see one, two or three of the numerals then by using % instead of the missing ones, the search would bring back all coins that could match?

Or does it already exist, and it doesn’t work for me?

As far as I know, the normal character to use as wildcard for a missing number or letter is: "*", not "%" but that doesn't work either.
