Knockout Array Filter on more than 1 Observable

I have an observableArray which I pass through the arrayFilter to return a filtered set. But I'm only doing it for 1 observable at the moment. How can I add a second observable:

return ko.utils.arrayFilter(self.complaints(), function (complaint) {
    return complaint.RaisedBy == self.currentUser();
});

So I also want to filter based on the Code property of my complaint object:

return ko.utils.arrayFilter(self.complaints(), function (complaint) {
    return complaint.Code == self.currentCode();
});

How can I combine them two?

Something like this should work:

self.myDependantObservable = ko.computed(function(){
   var currentUser = self.currentUser();
   var currentCode = self.currentCode();

   return result = ko.utils.arrayFilter(self.complaints(), function (complaint) {
     return (complaint.RaisedBy == currentUser && complaint.Code == currentCode);
   });

});

have you tried:

return ko.utils.arrayFilter(self.complaints(), function (complaint) {
    return complaint.Code == self.currentCode() && complaint.RaisedBy == self.currentUser();
});
