> Currently the concept of MapReduce shuffling is lumped into the *search*
> Streaming Expression. This causes quite a bit of confusion as users perform a
> search using the /select handler by default, but actually wanted shuffling
> behavior which requires the /export handler.
> We can solve this problem by creating a separate function called *shuffle*
> that always uses the /export handler.
> This will also allow us to clean up some behaviors in the search expression
> that are somewhat unexpected in future tickets.
> {code}
> parallel(workers,
> unique(shuffle(collection1,
> q=*:*,
> fl="id,a_s,a_i,a_f",
> sort="a_f asc, a_i asc",
> partitionKeys="a_f"),
> over="a_f"),
> workers="2",
> sort="a_f asc")
> {code}
