Hi, I am wondering what is the "best practice" of retracting one or more facts that fit a particular pattern. I am looking for something like this: (retract (car (make Honda) (model Civic) (year 1990)) The intention is to retract all car facts that satisfies a pattern. I am thinking writing a function that contains a query followed by a retract, but I am not sure if there are better/more clever ways to do this. Thanks.
