<p dir="auto"><code class="notranslate">/_cat/indices</code> currently allows returning an explicit set of headers in its output, such as health, status, index name, shard counts, etc. I'd love to see this endpoint support an additional header parameter: <code class="notranslate">?h=creation_date</code>.</p>
<p dir="auto">This would be useful for enumerating indices by age.</p>
<p dir="auto">Would be nice to provide an additional option for admins to return index.creation_date (from the index metadata) for the indices that are returned from the _cat/indices api.</p>
