Operators
Operators are symbols used in expressions and statements to perform a computation on or test a relation between data values or, in event expressions, to detect sequences and patterns of events. As you will see, the same symbol is sometimes used for different operations, depending on the context in which the operator is used. For example, the and operator is used both in logical expressions, and event sequencing and the * operator is used both for integer and floating point multiplication and to match any value in event templates.
