The following page has been changed by OtisGospodnetic: http://wiki.apache.org/solr/DistributedSearch ------------------------------------------------------------------------------ * The Facet component, for facet.query and facet.field requests where facet.sorted=true (the default) * The Highlighting component * the Debug component + + == Distributed Searching Limitations == + + * Documents must have a unique key + * When duplicate doc IDs are received, Solr chooses the first doc and discards subsequent ones + * No distributed idf (see http://wunderwood.org/most_casual_observer/2007/04/progressive_reranking.html ) + * Doesn't support !QueryElevationComponent + * Doesn't support consistency between stages, e.g. a shard index can be changed between STAGE_EXECUTE_QUERY and STAGE_GET_FIELDS + * Doesn't currently support date faceting + * Currently only supports sorted field facets + == Distributed Indexing == It's up to the user to distribute documents across shards. The easiest method to determine what server a document should be indexed at is to use something like '''uniqueId.hashCode() % numServers'''.
