   The FilterString method in RestEntitiesWebHandler tries to translate each field in the querystring to a bufferfield with BufferHelper:FieldWithSerializeName.
   This method returns ? when no match has been found.
   We now allow filtering on fields that are not part of the BE, but are so on DB level. As the method returns ?, this field gets quietly removed from the filter and no filtering occurs.
   Isn't it possible for BufferHelper:FieldWithSerializeName to return the SerializeName parameter back when no match is found in stead of unknown?
   If not, do you see another way to get the extra filter to the backend?

   Hi Bert, I really don't like the idea of auto-mapping database fields that are not part of the Business Entity for requests from a foreign system. 
   
   Why not include those fields in the Business Entity and set serialize-hidden to true? That way you keep control over the fields you can filter on.
   
   If you still need to influence the behavior, you can try to inherit from our web handler and override the FetchDataRequestFromRestRequest method.
