> Event(this after $b && $b after $a) If you read the drools manual you saw that all field expressions in drools have a field name as the left operand (note that "this" is a special field name). So you can't say "$b after $a". Nevertheless, even if it was possible to do what you want, it would be awful for performance, because you would be joining all events among themselves and only after joining, would the constraints be applied. Also, please note that Drools is FOL complete, so any FOL expression can be represented. Please read about the conditional elements too, not only restriction connectives && and ||.
