Actually, the blog post should still apply: just insert ToParent to rename things.
ToChildBlockJoinQuery is the same idea, but it joins in the reverse direction, so e.g. if your index has CDs (parent docs) and individual songs on those CDs (child docs), you can take a parent-level constraint (e.g. maybe price < $12) and join it down to child level constraints (maybe a query against the song's title) and then see individual songs (not albums) as the returned hits.
