Drools 5 supports backward chaining; Drools 4 does not.

There is no fuzzy logic. Facts, represented by Java objects (usually
JavaBean style) are, by definition, true; you never insert data representing
a false proposition.

Please explain what you mean by "intermingle". A Rule Base (preferably now:
Knowledge Base) contains rules; you create any number of sessions from that,
and each of these has its own Working Memory.
