EXAMPLES:

Simple:

rule: 3 > 2 AND 1 = 1
-> accept;

Black list check:

rule: inBlackList("email")
-> notify;

Counts check:

rule: (count("ip", 1444) >= 10 OR countSuccess("email", 1444) > 5)
        AND countError("fingerprint", 1444, "error_code") > 5
-> notify;

Unique count emails for ip:

rule: unique("email", "ip") < 4
-> decline;

Check country by ip:

rule: country() = "RU"
-> notify;

Check current amount:

rule: amount() < 100
-> accept;

Combined check:

rule: 3 > 2 AND 1 > 1
-> decline;

rule: count("email", 10) <= 10 AND count("ip", 1444) = 10
-> 3ds;
