title: MongoDB Bulkwrite which queries failed at match step?
body: <p>I am doing bulkwrite operation in MongoDB to update multiple documents at a time.</p>
  
  <p>Now Is there any way by which I can know which sequence number of my queries match step failed.</p>
  
  <p>Because in returned document I am getting <code>nModified</code>, <code>nMatched</code> which tells how many match failed, but not which query sequence number got failed?</p>
