<p dir="auto">Ability to collapse on a field. For example, I want the most relevant result from all different report types. Or similarly, the most recent result of each report type. Or maybe, I want to de-dup on headline.</p>
<p dir="auto">So, the sort order would dictate which one from the group is returned. Similar to what is discussed here:<br>

<p dir="auto">From my understanding, it seems that in order for field collapsing to be efficient, the result set must be relatively small.</p>
<p dir="auto">This is also referred to as "Combine" on some other search products.</p>
<p dir="auto">I restarted a node in my cluster but new documents are not indexing.  I thought "yellow' state meant that unassigned replicas are getting initialized but the cluster is still fully functional.  Is this a bug?</p>
