title: Elasticsearch log explanation
body: <p>I have enabled the slowlog for my elasticsearch server to see the traffic I get on it.

  <p>Does each of those lines mean (<code>index_3559_schema1, index_3559_schema1, index_3559_schema1</code>) I had an separate HTTP request?</p>
  
  <p>What is the difference between <code>index.search.slowlog.query</code> and <code>index.search.slowlog.fetch</code>?</p>
