[jira] [Commented] (OAK-8162) When query with OR is divided into
union of queries, options (like index tag) are not passed into subqueries.
[ https://issues.apache.org/jira/browse/OAK-8162?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16964823#comment-16964823 ]
Thomas Mueller commented on OAK-8162:
-------------------------------------
[~reschke] you are right, it would be good to backport this to Oak 1.10 and 1.8. I don't think Oak 1.6 is needed, as it doesn't support index tags. Do you want me to do this?
