Thanks for the test code. Please correct me if I am wrong. Per the doc of listStatements: Find all the statements matching a pattern.
My problem is that when I update the facts, this rule is not be triggered (executed). I assume this rule will be triggered every time when the fact is updated. On the other hand, a leading triple can bypass it. For example [test1: (a b ?c) now(?x) -> print(\"now test\") ]. When you update triple (a, b, xxx), the rule will be executed.
