How about:

    A message is called "excluded" if it matches at least one tag
    in search.tag_exclude that does not appear explicitly in the search
    terms.

Or less densely:

    Let "excluded tags" be the set of tags listed in search.tag_exclude,
    minus any tags which appear explicitly in the search terms.
    A message is an "excluded message" if it matches one or more
    excluded tags.
