    Description

      Our old behavior was that if two indexed field paths shared a common prefix, then only the first of those field paths appearing in the index would have its index bounds used for the query. With this ticket, if the index bounds for the two field paths come from the same $elemMatch clause then the index bounds on both field paths are used for the query.

      See SERVER-3104 for more details.
