Are rules checked in a particular order in a condition action?
If you have multiple rules as part of a condition action, they are not checked in any particular order.
By default, all rules must match for the action to emit an event. If you wish to match only a subset of the rules, for example, two of three rules, you can set that value in must_match.
If I use a condition with multiple rules, do all rules have to be matched or just one?
A condition with multiple rules acts in an AND fashion. All rules must be satisfied for the action to work.
You can use “must match” in an individual condition action to specify “OR” For example, using must match 1 acts as an OR.
