There are two supported wildcard characters for use in Message Tracker only in the following fields:
The wildcard characters are * and ?.
The * is used in place of multiple characters. The ? is used in place of a single character. For example, if searching for the word wildcard, you could type wildc*, where * is in place of ard. A search of this type finds all records beginning with wildc. You also could type wil?ca?d, where ? is a request to find any character in the specified positions.
There also is an escape character — the back slash \ — when the * or ? wildcards are needed as literal filtering conditions. For example, if you want to search for an asterisk as the literal part of a string, use \*.
