CEL issue when use ? symbol in filter

Hello!
We have 3 alarm classes in our project - alarms and two types of warnings.
When in CEL filter we select Alarm Classes = - All alarm classes and Indentification = *, only internal messages (with empty Identification field and message = Modify Spontaneous Value: (0.00000)) are shown in CEL.
When in CEL filter we select Alarm Classes = - All alarm classes and Indentification = ?*, messages of all classes are shown in CEL.
Is this correct?
