The "SolrCloud" page has been changed by Mark Miller: http://wiki.apache.org/solr/SolrCloud?action=diff&rev1=74&rev2=75 The Grouping feature only works if groups are in the same shard. Proper support will require custom hashing and there is already a JIRA issue working towards this. + == Glossary == + + Collection: A single search index. + Shard: Either a logical or physical section of a single index depending on context. A logical section is also called a slice. A physical shard is expressed as a SolrCore. + Slice: A logical section of a single index. One or more identical, physical shards make up a slice. + SolrCore: Encapsulates a single physical index. One or more make up logical shards (or slices) which make up a collection. + Node: A single instance of Solr. A single Solr instance can have multiple SolrCores that can be part of any number of collections. + Cluster: All of the nodes you are using to host SolrCores. + == FAQ == * '''Q:''' I'm seeing lot's of session timeout exceptions - what to do?
