[jira] [Commented] (LUCENE-7206) nest child query explain into
ToParentBlockJoinQuery.BlockJoinScorer.explain(int)
[ https://issues.apache.org/jira/browse/LUCENE-7206?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15291119#comment-15291119 ]
Ilya Kasnacheev commented on LUCENE-7206:
-----------------------------------------
NB: It should perhaps be
childWeight.explain(context, childDoc - context.docBase);
in the original patch in order for this to work over multiple segments.

> Now to parent query match is explained with {{Score based on child doc range from .. to .. }} that's quite useless.
> It's proposed to nest child query match explanation from the first matching child document into parent explain.
> WDYT?
