I am attempting to loop through the ChildScorer of the scorer.getChildren()
method inside my collect() call, and it is empty.
Is there something else I should do or some setup that I am missing?
Thanks
@Override
public void collect(int docID) throws IOException {
for(ChildScorer child : scorer.getChildren()){
System.out.println("relationship: " + child.relationship);
}
}

You could do this with a custom Collector which, for every hit visits all child
scorers asking each one whether it matched the current hit.
Your collector would have to somehow store this information away so that once
the search is done and you pull the top N hits, you know which fields those
hits had matched.
