Well, first the '?' character is invalid on filenames 
on many systems, including Windows/Msdos, and 
therefore should be avoided on other systems 
(Unix/Linux).
The query string can not be included using regular 
options - except parts of it - using %[name]

Example:
%h%p/%n%_[foo].%t

Will convert:
<http://www.abc.def/bar/smith.php?a=1&foo=45>
into
www.abc.def/bar/smith.php_45.html
