Mark Harwood commented on LUCENE-2454:
--------------------------------------

Sounds encouraging. I think the only thing 3171 may be missing from my original 
use cases then is that I can use multiple PerParentLimitedQueries in one query 
to get a limit of children of different types e.g. for each parent resume, max 
10 results from "employment detail" children and max 10 results from "education 
background" children.
Not sure that behaviour is possible in the collector-based approach?
