I'm trying to support queries on my facts with boolean operators. In a
simplified example, if someone asked me to search for
(dog AND cat) OR rabbit)
I want to search for facts that take either of the following two forms
(contains $?c&:(subsetp (create$ dog cat) $?c)
(contains $?c&:(subsetp (c
hi ,
thanks a ton.
The code is working fine and my problem is solved.

The boolean values in Jess are the atoms TRUE and FALSE. There are
boolean constants you can use in the Funcall class --
jess.Funcall.TRUE and Jess.Funcall.FALSE and public static Value
objects with the appropriate values, or just use new Value("TRUE", RU.ATOM).

Hi Guys,
I'm trying to write a few userfunctions that return boolean. Class Value does not have
a constructor that takes boolean, and RU does not have a boolean field. Is there
anyway around this?
Thanks

Sometimes I think that a short course in Boolean Logic might be applicable
BEFORE one engages in the task of writing a rulebased routine. Remember,
"Boole was no foole." :-)
