[17:06:21] <kempo> ahoji. when i am using the aggregation framework, is it possible to project all fields instead to specify them explicitely?
[17:07:10] <kempo> from the mongo docs: The _id field is, by default, included in the output documents. To include any other fields from the input documents in the output documents, you must explicitly specify the inclusion in $project.
[17:07:31] <kempo> but this seems not to be an elegant solution
