following expression, rather than after.

Repeat Set
Use the Repeat set options to find a character or wild card that appears a specified number of
times. To find parts of strings, be sure to uncheck Whole Word. You cannot use Repeat options in
the Replace expression. To replace something you find with a certain number of items in the
Replace box you must enter them that many times. (Remember, you can cut copy and paste in the
Find/Replace window.)
Repeat menu commands refer to repeated occurrences of a character or wild card. Zero or one
occurrences means that the character or string is either not found or found only once; there is no
repeat. For example, the expression
(find any A followed by any B which may or may not
be there), finds each occurrence of A alone or A preceding any number of B’s.
0 or 1 Zero or one occurrence
