Range indexes should support queries that use the $in and $eq operator in explicit encryption. Trying to encrypt the query below with explicit encryption on an encrypted index of type double raises an error.

"{ '$and': [{ 'encryptedDoublePrecision': { '$in': [{ '$numberDouble': '0.0' }, { '$numberDouble': '10.0' }] } } ] });"

The error message raised was: 

 unsupported operator: $in: { "$and" : [ { "encryptedDoublePrecision" : { "$in" : [ { "$numberDouble" : "0.0" }, { "$numberDouble" : "10.0" } ] } } ] }

The same error is raised for the $eq operator.
