   @JingsongLi At first glance, I guess the query is not supported. 
   However, after run it actually, The query could be executed, but results in error outputs.
   Because LookupJoin does not take filterNulls (which says k=v or k is not distinct from v) into consideration.
   
   Good catch, I will looks into the problem.
