title: show execution plan of a Oracle NoSQL query
body: <p>I am trying to validate the usage of an index but I cannot find a command allowing to show the current execution plan?</p>
  <pre><code>SELECT /*+ FORCE_INDEX(Persons idx_income) */ 
  * from Persons
  WHERE income &gt; 10000000 and age &lt; 40;
  </code></pre>
  <p>Is there a command to do this ? How to validate ?</p>
