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 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} was: Currently the concept of MapReduce shuffling is lumped into the *search* Streaming Expression.
