  The current components that support distributed search are
     * The Query component that returns documents matching a query
-    * The Facet component, for facet.query and facet.field requests where facet.sorted=true (the default)
+    * The Facet component, for facet.query and facet.field requests where facets are sorted by count (the default).  Solr 1.4 and later also support sorting by name.
     * The Highlighting component
     * the Debug component

     * 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
+    * The index could change between stages, e.g. a document that matched a query and was subsequently changed may no longer match but will still be retrieved.
     * Doesn't currently support date faceting
-    * Currently only supports sorted field facets
+    * Currently only supports sorted field facets (Solr 1.4+ supports both)

  Each shard may also serve top-level query requests and then make sub-requests to all of the other shards.
