<DL>
<DD>Returns a query expression that represents a matching constraint on
 a string argument. The matching syntax is consistent with file globbing:
 Supports "?", "*", "[", each of which may be escaped with "\";
 Character classes may use "!" for negation and "-" for range.
 (* for any character sequence ? for a single arbitrary character
 [...] for a character sequence).
 For example: a*b?c would match a string starting with the character a, followed
 by any number of characters, followed by a b, any single character, and a c.
