How do wildcards work?
+ Wildcards are used when you do not want to state exactly the numbers or characters to trigger a rule, but when there are specific alphanumeric characters that must be present. An example of this may be something like patient numbers, which, in a certain scenario, may always have the first five characters as HGTYU, but after those characters could be any combination of letters or numbers. So you could use HGTYU* to monitor emails leaving an organization that include this arrangement of characters.
