How do I find info on * and |?

I have been trying to find info on the correct usage of both the asterisk (*) and the vertical bar (|) inside the file groups. Would someone point me in the right direction (multiple locations would be appreciated)?

Thank you!

Only one post for | that I have seen is by Staff here.

Dennis2, thank you. Your reply helped.

I am surprised by the product documentation (or, more appropriately, the lack thereof). Correct usage of these symbols appears to be very important and determining the correct usage by trial and error or simply looking at examples makes me wonder if Comodo isn’t simply trying to press users into using GeekBuddy…

I will press on.
