      If mongoS changes the projection on a query, then the filters aren't applied to the query at all (mongoD runs the normal ranking process).

      The expected behavior would be either:

      1. Apply the filters as mongoD without the modified project (easier for users to understand)
      2. Apply the filters to query as given to mongoD from mongoS
