title: How to get the match scores for documents queried in Kibana
body: <p>I have setup my index in elastic search and have connected kibana to it. In the discover tab when i write a query i get my resulting documents which i know are sorted by a match score by Elasticsearch. How can i access this value in my visualizations? The _score field does not show up in the table format but does show up on clicking the JSON link.</p>
  
  <p>My vision is to present to the user a table based on the query criteria and the option to sort via the _score criteria.Does this make sense?</p>
  
  <p>Eg. for my query </p>
  
  <pre><code>first_name : Betty AND last_name: Campbell
  </code></pre>
  
  <p>I get <img src="https://i.stack.imgur.com/yLfrG.png" alt="enter image description here"></p>
  
  <p>And the score column is not visible.</p>
  
  <p>Any help is much appreciated.
  Thank you.</p>
  
  <p><strong>UPDATE:</strong>
  Managed to get the score field :
  In the setting tab in Kibana go to the metaFields section and add _score to it. Go back and query your data to see _score column waiting there for you.  But its not propagating to the visuals. And also its not showing very consistent behavior, after a random amount of time it just disappears from the discover tab but is still present in meta.</p>
