How to do an ElasticSearch Select Distinct : <p>I just want to do the following request with elasticsearch.</p>

<p>In SQL :</p>

<pre><code>Select distinct(id) from my_table where userid = '20' or activity = '9';
</code></pre>

<p>I just have :</p>

<pre><code>{
   "query" : {
        "bool" : {
               "should" : [ 
                  { "term" : { "userid" : "20" } }, 
                  { "term" : { "activity" : "9" } }
               ]
         }
    }
}
</code></pre>

<p>Thanks in advance :)</p>
