Joel Bernstein updated SOLR-10426:
----------------------------------
    Description: 
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.
