      Description

      validate() currently does an index scan of all the documents in a collection. It does not traverse every edge in the index tree structure. As a result, it's possible to corrupt the tree such that validate() will still succeed but querying for specific document(s) will fail. This behavior has been observed with the MMAPv1 storage engine.
