I'm not actually sure how the [0-9] or [a-z] filter works - if it matches a
single character/digit or if it's like a ([0-9]+) Regular Expression.  Xavier
should be able to clarify.

With the example you provided you could add a filter of:

-www.sswug.org/see/*

which would exclude ANY file under the "see/" directory level.  Any - not just
files with numbers in the name - so I don't know if you would want that, but
it may help.
