    Description

      Not sure if this is by design, a bug, or whether I am doing something wrong, but see findings in this thread:

      https://groups.google.com/forum/#!topic/mongodb-user/_3e0fmVorD0

      The use case where this comes into play is explained in the thread: "Using unset on a sparse index as an archiving alternative to two collections".
