[rules-users] Alternate approaches of using OR operator (to avoid sub-rule generation)

We are using Drools-3.0.6. In one of our scenarios, we are trying to use the OR operator as follows: rule Testing when person : (Person (interests contains "Golf") or Person (interests contains "Soccer") ) then System.out.println("I am interested"); end Based on one of my earlier posts in this forum (long time back), this rule will result in "The OR CE will cause subrule generation, meaning the rule will fire twice if both conditions are true". One of the ways, i was planning to change this is as follows: rule Testing when person : Person() then if (person.getInterests().contains("Golf") || person.getInterests().contains("Soccer")) { System.out.println("I am interested"); } end I don't think this is the best solution, though. Anyone has any better ways of implementing this? I know that Drools - 4 has a better support for this, but right now we don't have plans of migrating.
