      Original Downstream Change Summary

      Some $geoNear queries used to fail with IndexNotFound unnecessarily, in the case where there are multiple geo indexes and we thought we couldn't deduce which to use, even though some of the geo indexes were hidden so that we could deduce which to use. Now, those queries will not fail and will give correct results instead.

      Description of Linked Ticket

      Hidden indexes are supposed to be hidden from the query planner, however when there are 2 2d indexes with one hidden, the query planner fails with: "There is more than one 2d index"
