Hey Jason,
Yes, that is the case. Here are the basics around Wildcard use:
You can use an asterisk (*) to represent zero or more characters, and a question mark (?) to represent exactly one character.
There must be a minimum of three characters before an asterisk, and you cannot use it at the start of a word (but you can use it by itself with a space on either side to substitute for any single word). For example, the following search string returns hits for the words "make", "maker", "making", "The high road", "The low road", "wonder", "wondering", and so on:
[Any Of] mak*
The * road
Wonder*
Similarly, there must be a minimum of three characters between each instance of a question mark in the search string.
If it is specified in the From field, the following example finds items from users with an email address from "@acme.uk" or "@acme.hk":
[Any Of] @acme.?k
You cannot use either wildcard character after a special character, such as the ampersand (@). For example, the search string "@?cme.uk" does not produce the expected results.
