      Say we have {$or:[

      {a:1}

      ,

      {b:2,c:3}

      ]}. On the initial query most of the result may come from the

      {a:1}

      clause, and only a few results from the

      {b:2,c:3}

      clause. The selection of index

      {b:1}

      or

      {c:1}

      will be based on less data than it would be otherwise, and arguably shouldn't be recorded for future operations.
