The query can be as simple as *:* and I still get the error http://localhost:8983/solr/sial-catalog-material_shard1_replica1/select?q=*%3A*&fl=id%2C+sap_material_number%2C+material%2Cname&wt=json&indent=true&group=true&group.field=sap_material_number&group.limit=-1
Removing the group.limit and the query works. So group.limit in solrcloud will cause the failure. Specifically setting it to -1 is the cause. I think that the intent of the -1 was to get all of the documents but we do limit them to 500 in the ETL that loads solr On Thu, Mar 3, 2016 at 1:16 PM, WebsterHomer <webster.ho...@sial.com> wrote: > My company has a search application that we are trying to migrate to > solrcloud.
