Subject [Solr Wiki] Update of "DistributedSearch" by MarkusJelsma
Date Tue, 28 Feb 2012 10:34:08 GMT
Dear Wiki user,

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

The "DistributedSearch" page has been changed by MarkusJelsma:
http://wiki.apache.org/solr/DistributedSearch?action=diff&rev1=23&rev2=24

Comment:
Distributed data facetting is now supported since 3.6 and 4.0. Removed from list of limitations
and added to list of supported components.

  
  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 facets are sorted
by count (the default).  Solr 1.4 and later also support sorting by name.

faceting is supported since [[Solr3.6]] and [[Solr4.0]]. See issue [[https://issues.apache.org/jira/browse/SOLR-1709|SOLR-1709]].

     * The Stats component

     * Doesn't support MoreLikeThis -- (see https://issues.apache.org/jira/browse/SOLR-788
)
     * Doesn't support [[Join]] -- (see https://issues.apache.org/jira/browse/LUCENE-3759)
     * 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 (see https://issues.apache.org/jira/browse/SOLR-1709
)
     * Makes it more inefficient to use a high "start" parameter. For example, if you request
start=500000&rows=25 on an index with 500,000+ docs per shard, this will currently result
in 500,000 records getting sent over the network from the shard to the coordinating Solr instance.
If you had a single-shard index, in contrast, only 25 records would ever get sent over the
network. (Granted, setting start this high is not something many people need to do.)
