On the SolrCloud wiki page (https://wiki.apache.org/solr/SolrCloud), I found this statement:
The Grouping feature only works if groups are in the same shard. You must use the custom sharding feature to use the Grouping feature. However, the Distributed Search page (https://wiki.apache.org/solr/DistributedSearch) implies that grouping largely works, and the actual grouping page (or rather Field Collapsing: http://wiki.apache.org/solr/FieldCollapsing) goes into much more detail, outlining limitations on specific features. Am I right in assuming that the statement on the SolrCloud page is out of date? I'm happy to replace it with some text that links to https://wiki.apache.org/solr/DistributedSearch#Distributed_Searching_Lim itations if that makes more sense? Similarly, on the Distributed Search page, we find: Doesn't support MoreLikeThis -- (see https://issues.apache.org/jira/browse/SOLR-788) Looking at the issue, it seems this has been (largely?) resolved since Solr 4.1 and 5.0. Can I update the text to reflect that? Thanks for your time.
