[jira] [Created] (LUCENE-4077) ToParentBlockJoinCollector provides
no way to access computed scores and the maxScore
Christoph Kaser created LUCENE-4077:
---------------------------------------
Summary: ToParentBlockJoinCollector provides no way to access computed scores and the maxScore
Key: LUCENE-4077
URL: https://issues.apache.org/jira/browse/LUCENE-4077
Project: Lucene - Java
Issue Type: Bug
Components: modules/join
Affects Versions: 3.6, 3.5, 3.4
Reporter: Christoph Kaser
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

Woops, you're right, thanks. In fact I should be passing the maxScore that the collector already computed, not recomputing it in ToParentBJC.getTopGroups...

Christoph Kaser commented on LUCENE-4077:
-----------------------------------------
Hi Mike,
shouldn't TopGroups.maxScore contain the maximum parent score? If I am not mistaken, the way it is built now, it contains the maximum child score over all children.
This is due to this line in ToParentBlockJoinCollector.getTopGroups():
{code}
maxScore = Math.max(maxScore, topDocs.getMaxScore());
{code}
I think it should read:
{code}
totalMaxScore = Math.max(totalMaxScore, og.score);
{code}
Otherwise, topGroups.maxScore is different to ToParentBlockJoinCollector.getMaxScore()

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.

Patch.
I added getMaxScore to ToParentBlockJoinCollector, and GroupDocs.score to access the aggregated score for the group. I also added a ScoreMergeMode enum to TopGroups.merge to control how the scores from the same group across multiple shards should be merged.
