Elasticsearch query based on result of initial query
<p>I have an interesting problem, I have an Elasticsearch query which brings back whatever results, however, some of these results have have other results associated with them, like comments associated with a forum post. </p>

<p>If a forum post is matched by my query, I want it to also match the associated comments, which all have a <code>parent_id</code> of the original forum post. </p>

<p>Is that possible? </p>
