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.
