Dear Wiki user,

You have subscribed to a wiki page or wiki category on "Solr Wiki" for change 
notification.

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'''.
