-----------------------------------
Summary: child documents lack _version_, susceptible to reordered
delete-by-query
Key: SOLR-10114
URL: https://issues.apache.org/jira/browse/SOLR-10114
Project: Solr
Issue Type: Bug
Security Level: Public (Default Security Level. Issues are Public)
Reporter: Yonik Seeley
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.
