不使用 declare salience 执行订单规则

Question

那就是问题所在，假设我有 2 条规则。第二条规则依赖于第一条规则。例如：

 (deftemplate person 
(slot name (type STRING))
(slot age (type STRING))
)

(deffacts start
 (person(name "Mike")(age "20"))
 (person(name "Laura")(age "22"))
 (person(name "Dean")(age "22"))
 (person(name "Charlie")(age "22"))
 )

 (defrule filterage
 (person (name ?n)(age ?a))
 (test (eq ?a "22"))
 =>
 (assert (is-equal-to-22 ?n))
 )

 (defrule creategroup
 (is-equal-to-22 ?c)
 =>
 (assert (is-in-22-years-old-group ?c))
 )

正如预期的那样，只要有来自规则 1 的内容，第二条规则就会触发。

那么，我怎样才能让第二条规则等到所有人都被创建，而不使用 declare salience
