Not sure if this will work. I can be passing 1 of 2 parms in the url. The parms both work individually if I remove the other query One value passed is call “Id” and the other is “Person_Id”. I tried using and each is set to “abort this models query” I either pass the Id or Person_Id. I would think the one not passed would yield the others result. There can be no matches.
