Questions on nested child document split using the "split" parameter
I am trying to find more information regarding this upgrade in Solr 8.0.0,
but I could not really understand what it means, and couldn't find much
information on that, especailly that the Solr User Guide for 8.0.0 is not
SOLR-12633 <http://issues.apache.org/jira/browse/SOLR-12633>: When JSON
data is sent to Solr with nested child documents split using the "split"
parameter, the child docs will now be associated to their parents by the
field/label string used in the JSON instead of anonymously. Most users
probably won't notice the distinction since the label is lost any way
unless special fields are in the schema. This choice used to be toggleable
with an internal/expert "anonChildDocs" parameter flag which is now gone.
Will it affect the query or output of the nested child documents?
