<br> No, you need to identify which object are you trying to retract, since you may have multiple facts constrained in the LHS.<br><br> Regarding your problem, make sure your rules file has the extension ".dslr" so that eclipse selects the correct editor when opening the file. Then click in the DRL preview in the editor bottom tab. Can you please show me the result of the DRL preview?

Yes, that is correct. <br>
Why do you mean by a "cleaner" way?<br>
