[rules-users] confusing world of drools

hello, i think they have made so powerful that it is to abstract to understand.   following: all i would like to do is magage a large number of rules under a set of "rule sets"   each rule set can have many rules   each rule can belong to one or multiple sets   or a many to many relationship.   i expect for a given rule set id, that the corresponding rules to be executed. i dont see yet how this is done in drools under the current documentation.   thank you for any help
