Christoph Kaser commented on LUCENE-4077:
-----------------------------------------
Hello Mike,
thank you for the patch. There is one small problem:
ToParentBlockJoinCollector.getMaxScore() always returns _NaN_. This happens
because maxScore is initialized as
{code}
private float maxScore = Float.NaN;
{code}
and then updated as
{code}
maxScore = Math.max(score, maxScore);
{code}
which is always _NaN_.
I hope I applied the patch to the correct revision and this is not caused by a
version conflict.

> The constructor of ToParentBlockJoinCollector allows to turn on the tracking
> of parent scores and the maximum parent score, however there is no way to
> access those scores because:
> * maxScore is a private field, and there is no getter
> * TopGroups / GroupDocs does not provide access to the scores for the parent
> documents, only the children
