Andreas Hubold updated SOLR-15468:
----------------------------------
Description:
In previous Solr releases (8.6.3) it was possible to add the \_root\_ field to
the schema of an existing index, e.g to add functionality relying on child
documents without reindexing all documents.
This does not work anymore with Solr 8.8.2, because SOLR-14923 added a check in
RealTimeGetComponent#getInputDocument that the root field contains the expected
value. IIUC, the check does not only fail for wrong values, but also if the
root field does not contain any value yet, as it's the case for documents that
were added before the field was added to the schema.
The check causes atomic/partial updates to fail:
{noformat}
Caused by: org.apache.solr.common.SolrException: Attempted an
atomic/partial update to a child doc without indicating the _root_ somehow.
