So really I should test block join against collapse with an index where groups 
have not been blocked indexed.

> There are scenarios where documents are partitioned across shards based on 
> the same field that the *unique* agg is applied to with JSON facets. In this 
> scenario exact unique counts can be calculated by simply sending the bucket 
> level unique counts to the aggregator where they can be summed. Suggested 
> syntax is to add a boolean flag to the unique aggregation function: 
> *unique*(partitioned_field, true).
> The *true* value turns on the "partitioned" unique logic. The default is 
> false.
