Wildcard Operators when using "matches" in Segment Builder
Which wildcard operators are supported in Segment Builder?
Looking through the posts returned by this search and having done some experimentation, I suspect the asterisk (*) character is the only one (i.e. "matches zero or more of any character").
However, my reason for asking is that the Comparison Operators for Segment help article makes reference to "wildcard operators" (in the plural) and the concept of "globbing" (which is much more extensive than the simple asterisk).
