I have a use case which requires collapsing on multiple fields.

As a simple example assume I have some movie documents indexed with the  
fields: Director, Actor, Title & Release Date. I want to be able to  
collapse on Director and Actor, getting the most recent movie (as indicated  
by Release Date).

I think the new top hits aggregation almost gets me mostly what I need. I  
can create a terms aggregation on Director, with a sub terms aggregation on  
Actor, and add a top hits aggregation to that (size 1). Would this be the  
proper approach? By traversing over the aggregations I can get all of the  
hits that I want - however I can't (have elasticsearch) sort or page them.

It's almost like I'd need a "hitCollector" aggregation which would collect  
all search hits generated by it's sub aggregations and allow me to specify  
sort and paging information at that level. Thoughts?

Brian
