That's the hackish solution introduced initially by Abdullah, and reused here 
for my needs.
It removes secondary metadata indexes from consideration, because they do no 
provide the valid types for indexed fields, thus breaking type validation logic 
underneath.
I am not a big fan of this solution, but this is as far as I can get without 
redesigning secondary metadata indexes implementation.
