> It looks like when a block of documents is indexed, child documents get no \_version\_
field.  This means (among other potential issues) that a delete-by-query that is reordered
will cause matching child documents to be deleted.  DBQ normally prevents deleting newer docs
by including a restriction on \_version\_, which doesn't work for anything lacking that field.
 Re-ordered delete-by-term of any child docs would also be affected (although it should be
a much rarer issue.)
> The leading candidate for a fix is to use the exact same \_version\_ for all child docs.
