You're right Paul. I forgot to specify that the string inside the parentheses must not contain parentheses. Otherwise I get unwanted results:

Find = \(*[0-9]{4}*\)

This view provides hope (of winning the lottery, etc.) and makes the
world less scary and more predictable and comfortable. Indeed,
considerable evidence suggests we are more effective, more
responsible, and happier when we feel we are partially in control, i.e.
have made the decisions and carried out the plans for changing things
(Deaux and Wrightsman, 1984). But, of course, it is usually impossible
to know exactly how much of our good fortune is due to our efforts
and how much is due to others, fate, or chance. It is, to some extent,
a matter of "beliefs."

Thanks.
