Description

Spinning off from SOLR-9314...

The [subquery] DocTransformer can give unexpected results when used with RTG on uncommitted docs.

Test code demonstrating the problem is being added to TestRandomFlRTGCloud as part of SOLR-9314, but it's being disabled for now due to this current bug. As noted in that jira...

The subquery validation tries to search for all docs with teh same field value as the current doc, asserting that there is always at least 1 match – but this assertion currently fails ... by the looks of it this is (obviously) because it doesn't know to to use the realtime seracher re-opened by the RTG ... but based on how the SubQueryAugmenter is implemented, i'm not even certain how to go about it.
