By default, all constraints must be satisfied for the reaction to occur. In other words, constraints are evaluated as a series of logical values using the logical AND operator "&&". More complex logic -can be achieved by explicitly adding "&&" or "||" after a given -constraint command. Logical operators must be placed after all -constraint parameters, on the same line as the constraint (one per -line). Similarly, parentheses can be used to group constraints.
