Ticket: Faceted Search
Please append the skipStage, limitStage, and facetStage to the queryPipeline
(in that order). You can accomplish this by adding the stages directly to
the queryPipeline.
The queryPipeline is a Javascript array, so you can use push() or concat()
to complete this task, but you might have to do something about `const`.
