Hello,
When trying to perform an atomic update on a document belonging to an
upgraded index, the following error occurs: "Attempted an atomic/partial
update to a child doc without indicating the _root_ somehow"; although we
are not trying to update a document having nested docs. I have attached a
piece of the Solr log for the error stacktrace. We have the "_root_" field
configured in the schema.xml, since we use nested docs, but the update is
not done on a document containing nested docs. The configurations for
version and root fields:
<field name="_version_" type="plong" indexed="true" stored="true"
docValues="false" />
<field name="_root_" type="string_for_id" indexed="true" stored="false"
docValues="false" />
where string_for_id is of type solr.StrField.
The issue seems to apply only to documents originating from an upgraded
index, and doesn't manifest itself all the time, but quite often though.
Any ideas about what might cause this problem?
If you need additional information please let me know.
Thanks,
Branco
