Someone is searching for the following string. Could you please
explain the "@" and the "\". I'm not quite sure what this means.
Thank you for your help.
"\*{3}[A-Za-z0-9]@\*{3}"
This is a wildcard string. The two-character code \* means an actual
asterisk character The asterisk by itself is a wildcard meaning "any group
of characters", so the backslash says "don't treat the asterisk as a special
wildcard, just a plain asterisk".
The @ symbol means "one or more characters that match the preceding
expression", where the preceding expression is [A-Za-z0-9] which translates
as "any upper or lower case letter or digit".
