Many rules matching only one subject

[james-evidation]

Hi,

I have many criteria as rules and I want to match a user to these criteria. e.g.

engine << ["user", "age", 20]
engine << ["user", "state", "CA"]
engine << ["user", "weight", 130]

and I have many rules like the following
forall {
has :A, "age", :Age
less :Age, 30
greater :Age, 20
has :A, "state", "CA"
}

At any point in time there will only be one user.
Is there a way to do this matching more efficiently without having to loop through each rule? Typically one would match a rule to many subjects but I want to do this the other way around, find which rules the subject agrees with.
I tried to have the criteria expressed as facts and the user attributes be rules but I have found it to be difficult to construct combinations.

Thanks!
