Hi Ludger, We had the same issue with Solr 7.6, and after discussing with the community we've found out that this partial update of parent document without "harm" parent-child association can work only on Solr 8.1 or higher, and It also requires some prerequisites.
See the below item and it's last comments with details: https://issues.apache.org/jira/browse/SOLR-12638?focusedCommentId=16894628&page=com.atlassian.jira.plugin.system.issuetabpanels%3Acomment-tabpanel#comment-16894628 Eventually we have move to Solr 8.3 and it's working there as expected with the above mentioned changes.

Suppose I have committed the following documents to the index: [ { "id": "1", "testString": "1", "testInt": "1", "_childDocuments_": [ { "id": "1.1", "child_type": "child_a", "testString": "1.1", "testInt": "1" }, { "id": "1.2", "child_type": "child_a", "testString": "1.1", "testInt": "1" } ] } ] <uniqueKey> is id, all fields are indexed. Now I want to update testInt to 2 on the parent document without losing the parent child relation (ChildDocTransformerFactory should still produce correct results). I tried the following variants, both not successful: *Variant 1:* Sending the following update document to the update-Endpoint [ { "id": "1", "testInt": { "set": "2" } } ] The parent document is updated, but the ChildDocTransformerFactory does not return any child documents *Variant 2:* Sending the following update document to the update-Endpoint [ { "id": "1", "testInt": { "set": "2" }, "_childDocuments_": [ { "id": { "set": "1.1" } }, { "id": { "set": "1.2" } } ] } ] Same result: Parent is updated, but ChildDocTransformerFactory does not return any child documents Is there any other way of doing a partial update without losing the parent child relation? Resending the complete document with all attributes and children would work but is inefficient for us (we had to load all documents from Solr before resending them). Thanks in advance for your help Ludger ------------------------------ *„Beste Arbeitgeber ITK 2020“ - 1.
