sadly, this is expected. It's not only parent-join, but any kind of approximate NN search. Think of the limit where we have as many segments as there are documents, recall will always be 100% because we will perform a "brute force" index scan. If we want to figure out how to maintain the same recall as the index merges, that would be an interesting problem? The pro-rata collection method we've switched to now will tend to reduce the work done per segment as the segments shrink, but it has enough of a buffer that I think we'd still see this effect. -- This is an automated message from the Apache Git Service.
