5.4 Operators

Each data type has specific operators that can be used with a given keyword.

This section covers the following topics:

UNARY keywords have no operators (or Value data). Follow a UNARY keyword filter expression with either a Closing Parenthesis or another Simple Statement. For example, the filter expression "(APPOINTMENT)" will find all Appointment messages.

There is one exception to this rule. The NOT operator can proceed a UNARY keyword. The following are a few examples:

To find all messages that are not appointments, use (NOT APPOINTMENT).
