Shawn Heisey commented on SOLR-13980:
-
I have never actually used the parent/child document support, so consider that
when reading below:
It's my understanding that all documents in a parent/child relationship must
reside in the same Lucene index segment. If I'm reading your schema correctly,
the color_s field is not eligible for in-place updates. Which means that when
you do that update, the original document is marked as deleted and a new one is
indexed into another segment – which means that the same-segment requirement
has not been met. I think that's the root of the problem here.
Only barely related: Jira is not a support portal for the Solr project. When
you created this issue, there was a prominent note in red text explaining this.

> Hi Team,
> We are trying to update only child or parent document in solr 8.3 version as
> per the example mentioned in
> document:[https://lucene.apache.org/solr/guide/8_3/updating-parts-of-documents.html]
> , but the issue we facing is child or parent document alone not getting
> updated.
> When we query using parent child query not retuning updated value , but when
> we query using q=*:* in debug mode enabled , document count got increased by
> 1 .i.e. 3 to 4 but its not replace right child doc.
> Can you please let us know is there any other configuration need to be added
> to support feature (or) child or parent document only update feature not
> supported currently ?
> *+Configuration:+*
> Running locally in SolrCloud mode with 4 Shards and 2 Replication factor ,
> using external zookeeper.
> Attached solr-config.xml , managed-schema.xml , parent child query output in
