Hi Jean-Sebastien, For some grouping features (like total group count and grouped faceting), the distributed grouping requires you to partition your documents into the right shard. Basically groups can't cross shards. Otherwise the group counts or grouped facet counts may not be correct. If you use the basic grouping functionality then this limitation doesn't apply.
I think right now that SolrCloud partitions documents based on the unique id (id % number_shards). You need to modify this somehow or maybe do the distributed indexing yourself.
