title: How does elasticsearch multi search work?
body: <p>How does it work in the background?
  Lets say it has two queries.
  Would the total time taken be</p>
  
  <p><strong>1) network latency + time for query1 + time for query2</strong></p>
  
  <p>or</p>
  
  <p><strong>2) network latency + max(time for query1, time for query2)</strong></p>
  
  <p>I am assuming its the later but couldn't find any documentation to confirm that.</p>
