The Luke Request Handler returns duplicate object keys in the JSON response
for multiValued fields. Only the last value survives the trip through a

Hi,
I use only one solr instance. I want to use IndexUpgraderTool to migrate
from Solr 7.6 to 8.11.1. Is there any problem when migrating fields with

documents, then you should be all set.
You should be able to page through your entire index with ordinary &start= and
&rows= params, but if y
