      I think the easiest way is to try running existing tests: first, apply this patch to run with multiple shards:

      As part of SERVER-31785, I noticed that an aggregation like

      db.coll.aggregate({$match: {$text: {$search: "foo"}}});

      will return the text score even though it hasn't been requested. This seems like a bug, as it differs from the behavior of the find command, which does not return the text score. Interestingly, this only occurs when the query targets multiple shards in the cluster. If I add a predicate on the shard key and target one shard, the text score is not included.

      charlie.swanson noted that this might be related to the change in SERVER-22760, which allows merging on mongos for certain pipelines. I've confirmed that this doesn't reproduce when setting internalQueryProhibitMergingOnMongoS, so we should investigate the mongos merging logic.
