The following page has been changed by Lance Norskog: http://wiki.apache.org/solr/LargeIndexes ------------------------------------------------------------------------------ '''DistributedSearch''' '''Faceting'''[[BR]] - DistributedSearch merges facet results (see the page for limitations). (Please comment on implications for huge facet result sets. It seems like memory usage in merging by count and merging by name have an equal upper bound, but the average case will require very little memory for merging by name.) + DistributedSearch merges facet results (see the page for limitations). ''(Please comment on implications for huge facet result sets.

Vertical Partition'''[[BR]] In database jargon a "horizontal partition" splits record sets into multiple stores, while a ''vertical partition'' splits each row into multiple pieces and stores each piece in a separate database, cross-connected by the primary key for the record. DistributedSearch provides a ''horizontal partition''. There is no implementation of a vertical partition across indexes.
