      SERVER-86732 implemented an algorithm to compute the minimum and maximum constraints of documents needed to satisfy a query. Currently, $facet is treated as a blackbox where all constraints are treated as unknown. We could traverse the $facet subpipelines to infer constraints on each subpipeline then compare to gather more precise constraints for the overall pipeline.
