Mark Harwood commented on LUCENE-2454:
--------------------------------------

I'm not sure the auto-repair is that trivial.
Let's say the parent/child docs are resumes and nested docs for employment positions \
(as in the attached example). An update may not just be adding a new "employment \
position" doc but editing an existing one, deleting an old one etc. Your auto-updater \
is going to need to do a lot of figuring out to work out which existing docs need \
copying over from earlier segments and patching in to the new segment with the \
updated parts of the resume. This gets worse if we start to consider multiple levels \
to the hierarchy. It all feels like a lot of work for the IndexWriter to take on?
