JESS: Retracting large number of facts

[Mithun Sheshagiri]

Hi all,
            I am developing an application that involves a large number 
of transient facts. Addition of facts is obviously not a problem; 
deletion is a bit tricky. I was trying to make use of the logical 
construct to remove facts.

for example, (defrule yo
                    (logical (foo bar))=> (assert .......)
So by retracting (foo bar), I can retract (I think) arbitrary number of 
facts.. By using this technique, I have to remember just one fact-id to 
delete a large number of facts. But there is a problem with the 
"logical" construct which has been reported and fixed in the 6.1p7 version

The other ways of doing it (which I know about) are:
1.  To store the fact-id/of all the facts and use the retract command
2. Somehow get hold of the string representation of the facts and use 
the retractString command.

Is there a better way of removing facts.
I own the book "Jess in Action" and therefore have a 6.1p4 version of 
Jess. Is there a legitimate way of getting my hands on Node1RTL.class 
which fixes the bug with the logical construct.

peace
