the more general query works fine.  the problem you pointed out is  
that there are a large number of unnamed things and a lot of people so  
the intersection times out.  but finding all the unnamed things is  
doable.  you can add language constraints etc without it timing out.

[
   {
     "/type/object/name" : {
       "optional" : "forbidden",
       "value" : null
     },
     "id" : null
   }
]
