Where most metric aggs reduce a bucket to one number, <code>top_hits</code> keeps the documents themselves.</p> <h2 id="how-it-works"> How it works <a class="anchor" href="#how-it-works">#</a> </h2> <p><code>top_hits</code> runs over a bucket&rsquo;s document set and returns up to <code>size</code> documents in a hits envelope: <code>hits.total</code> — a plain count of the bucket&rsquo;s documents — and <code>hits.hits[]</code>, each entry carrying <code>_id</code> (the engine&rsquo;s internal numeric document id) and <code>_source</code>.</p>
