No.

A trailing "?" at the end of searchstring matches all digits or the "?" 
itself.

Example: 
"refdes=U?" will renumber all text elements that start with "refdes=U" 
and ends with either a "?" or at least one digit "[0-9][0-9]*"

A trailing "*" at the end of the searchstring will build a list of all 
matching prefixes before renumbering them.

Example:
"refdes=D*" will lead to many search strings that starts 
with "refdes=D[^0-9?]*" -->"refdes=D", "refdes=DZ", "refdes=Dxxx"

With each searchsting the renumber action is executed as described with 
the trailing "?".

See gschem/src/x_autonumber.c, function autonumber_text_autonumber() for 
more details.

Regards
Werner
