How to add multiple exists fields with OR operation in elasticsearch : <p>I have the following query:</p>

<pre><code>{
  "query": {
    "exists": {
      "field": "field1"
    }
  }
}
</code></pre>

<p>I would like my query to be modified in a way that I could add another filter with existing field having 'OR' operation between them.</p>

<p>Any idea how to do so?</p>

<p>Thanks.</p>
