Keep an eye on the asterisks that you are putting in $search_string, too. An asterisk means 'match the preceeding element 0 or more times, so the asterisk in 'C04*' means 'match the digit 4 zero or more times'.

An asterisk in 'C04\w*' would mean 'match any alphanumeric character (or underscore) zero or more times.
