Filter Criteria Does Not Work

Content

Hi All,

Filter Criteria works perfect when i use single variable, but if i use multiple , it does not work.

Can you please tell where iam going wrong, and how do i trace how this criteria is passed to BO at run time.

Do we have any logging mechanism to find out it ?  So i can have clear understanding of it.

   },
   {
    "op": "$co",
