Need to do some tasks if customers age is in 18,21,33,28,40,41. Can't use
contains as age is a string value.Could any one help me out. Below rule does
not work.
rule "Age Factor"
when
m : Customer( age matches "18,21,33,28,40,41")
then
System.out.println("Customer falls in age group ");
doAgeTasks();
end
Thanks,
Lindy.

I think that you can do something like:
m : Customer( age == "18" || =="21" || =="33" ||
=="28" || =="40" || =="41")

Yes Rete Tree is identical for both the structures. Will go with one of the
scenarios given below , instead of going with Regex.
rule "Test"
when
t : Thing( foo == "BAR" || == "BAS" );
then
System.out.println( "meh" );
end
rule "Test"
when
t : Thing( foo in("BAR","BAS") );
then
System.out.println( "meh" );
end
Adding to my initial question , based on the condition satisfied how can I
set a variable to "Y"in a different object (Other than
customer)?customerDetail is not static.
rule "Age Factor"
when
m : Customer( age matches "18,21,33,28,40,41")
then
System.out.println("Customer falls in age group ");
// doAgeTasks();
customerDetail.setFallsInAgeGroup("Y"); -- Need to do something like
this.How can I do this?

There must be some link between a customer's Customer and CustomerDetail facts.
when
$m : Customer( $id : id, age matches "18,21,33,28,40,41")
$d : CustomerDetail( id == $id )
then
$d.setFallsInAgeGroup("Y");

Problem is Customer & CustomerDetail are not related. Is there any work
around? Also I looked at the rete tree for matches using Jared Davis's mail
, this also results in the same identical structure as with | or in.

So is there only one CustomerDetail, or are there many? If so, how do you think
you can retrieve that data to use whatever is stored in there? This
sounds strange...

There is only one CustomerDetail, receive Customer object in request and
CustomerDetail is response. There is only referenceId that is common in both
the objects, probably I can use that as the link between two objects.

Here are two ways to write the regular expression.
m : Customer( age matches "(18|21|33|28|40|41)")
m : Customer( age matches "(18|2[18]|33|4[01])")
Did you try
m : Customer( age in
("18","21","33","28","40","41"))
I don't know which solution is faster. I think that would
be an interesting test.

@Greg
Using "in" is better that the multiple || == "18" ?
It has some relation with indexing?
With multiple "|| == " the RETE network will generate one alpha node for
each value right?
But for "in" I don't imagine how it works, I also realize that it's not
included in the official docs.

The rete view for the following two rules have identical structure: (One alpha node in
each)
rule "Test"
when
t : Thing( foo == "BAR" || == "BAS" );
then
System.out.println( "meh" );
end
rule "Test"
when
t : Thing( foo in("BAR","BAS") );
then
System.out.println( "meh" );
end
So I guess the "|| ==" conditions are combined into one node. I can't peek
into the source at the moment to check, though. And I don't know which is faster.
I'd guess that either is faster than regex for short lists, though.

Use the "in" keyword:
rule "Age Factor"
when
m : Customer( age
in("18","21","33","28","40","41")
)
then
System.out.println("Customer falls in age group ");
doAgeTasks();
