Parent child search (kind of like outer join)

Hi

As per release notes for 0.14, one of the features (for parent/child)
that is being implemented is "returning the child docs as part of the
search request".
Any ideas when I should expect it to be there?

Currently I am trying to do a query on child table using "must" on
parentId field and "should" on child fields wrapped in a bool query,
but that does not return the parent, so have to do another query for
that. Anybody know of a better way.

Thanks
