> The sort Streaming Expression does an in memory sort of the Tuples returned
> by it's underlying stream. This is intended to be used for sorting sets
> gathered during local graph traversals. This will make it easy to gather sets
> during a traversal and use all of the sort based set operations (merge,
> innerJoin, outerJoin, reduce, complement, intersect).
> This will be particularly useful with the gatherNodes expression (SOLR-8925).
> Sample syntax:
> {code}
> intersect(
> sort(gatherNodes(...), "fieldA asc"),
> sort(gatherNodes(...), "fieldA asc"),
> on)
> {code}
