Looks like there are two distinct filter types: nodeRange and traceId
How about introducing another class for allocation node id filter?

I will need to filter by both id range and allocation id so I'd rather leave
this in a single class.

     equals: function(o)
     {
-        return this.minNodeId === o.minNodeId && this.maxNodeId === o.maxNodeId;
+        return this.minNodeId === o.minNodeId && this.maxNodeId === o.maxNodeId && this.allocationNodeId === o.allocationNodeId;
     }
