In the expressions you may enter parentheses to group sub-expressions together. Together with
the supported list of operators this gives great flexibility in constructing advanced “match”

Table 8.2

below are used for illustration purposes only. For example, the plus and minus operators may
not be very useful in practise, but they are included in this table for completeness.
