+<h1>Apache Solr Release Notes</h1>
+
+<div id="buttons.parent"></div>
+
+<h2>Introduction</h2>
+ <p>Apache Solr is an open source enterprise search server based on the Apache Lucene Java
+search library, with XML/HTTP and JSON APIs, hit highlighting, faceted search,
+caching, replication, and a web administration interface. It runs in a Java
+servlet container such as Tomcat.
+</p>
+ <p>See <a href="http://lucene.apache.org/solr">http://lucene.apache.org/solr</a> for more information.
+</p>
+<h2>Getting Started</h2>
+ <p>You need a Java 1.6 VM or later installed.
+In this release, there is an example Solr server including a bundled
+servlet container in the directory named "example".
+See the tutorial at <a href="http://lucene.apache.org/solr/tutorial.html">http://lucene.apache.org/solr/tutorial.html</a>
+</p>

+ <li>Custom java parsing plugins need to migrate from throwing the internal
+ParseException to throwing SyntaxError.
+</li>
+ <li>BaseDistributedSearchTestCase now randomizes the servlet context it uses when
+creating Jetty instances. Subclasses that assume a hard coded context of
+"/solr" should either be fixed to use the "String context" variable, or should
+take advantage of the new BaseDistributedSearchTestCase(String) constructor
+to explicitly specify a fixed servlet context path. See <a href="http://issues.apache.org/jira/browse/SOLR-4136">SOLR-4136</a> for details.

+regular field value faceting can. This means support for excluding a filter
+query, using a different output key, and specifying 'threads' to do
+facet.method=fcs concurrently. PivotFacetHelper now extends SimpleFacet and

+For example if replicationFactor=3 then for a given shard there

+<br /><span class="attrib">(Shahar Davidson via shalin)</span></li>
+ <li><a href="http://issues.apache.org/jira/browse/SOLR-2592">SOLR-2592</a>: Collection specific document routing. The "compositeId"
+router is the default for collections with hash based routing (i.e. when
+numShards=N is specified on collection creation). Documents with ids sharing
+the same domain (prefix) will be routed to the same shard, allowing for
+efficient querying.
+<p/>
+Example:
+ The following two documents will be indexed to the same shard
+ since they share the same domain "customerB!".
+ <code><pre>
+ {"id" : "customerB!doc1" [...] }
+ {"id" : "customerB!doc2" [...] }</pre></code>
+ At query time, one can specify a "shard.keys" parameter that lists what
+ shards the query should cover.
+ <a href="http://.../query?q=my_query&shard.keys=customerB!">http://.../query?q=my_query&shard.keys=customerB!</a>
+<p/>
+Collections that do not specify numShards at collection creation time
+use custom sharding and default to the "implicit" router. Document updates
+received by a shard will be indexed to that shard, unless a "_shard_" parameter
+or document field names a different shard.

+ <li>Solr is now much more strict about requiring that the uniqueKeyField feature
+(if used) must refer to a field which is not multiValued. If you upgrade from
+an earlier version of Solr and see an error that your uniqueKeyField "can not
+be configured to be multivalued" please add 'multiValued="false"' to the

+ <li>The Lucene index format has changed and as a result, once you upgrade,
+previous versions of Solr will no longer be able to read your indices.
+In a master/slave configuration, all searchers/slaves should be upgraded
+before the master. If the master were to be updated first, the older
+searchers would not be able to read the new index format.
+<p/>
+</li>
+ <li>Setting abortOnConfigurationError=false is no longer supported
+(since it has never worked properly). Solr will now warn you if
+you attempt to set this configuration option at all. (see <a href="http://issues.apache.org/jira/browse/SOLR-1846">SOLR-1846</a>)
+<p/>
+</li>
+ <li>The default logic for the 'mm' param of the 'dismax' QParser has
+been changed. If no 'mm' param is specified (either in the query,
+or as a default in solrconfig.xml) then the effective value of the
+'q.op' param (either in the query or as a default in solrconfig.xml
+or from the 'defaultOperator' option in schema.xml) is used to
+influence the behavior. If q.op is effectively "AND" then mm=100%.
+If q.op is effectively "OR" then mm=0%. Users who wish to force the
+legacy behavior should set a default value for the 'mm' param in
+their solrconfig.xml file.
+<p/>
+</li>
+ <li>The VelocityResponseWriter is no longer built into the core. Its JAR and
+dependencies now need to be added (via <lib> or solr/home lib inclusion),
+and it needs to be registered in solrconfig.xml like this:
+ <queryResponseWriter name="velocity" class="solr.VelocityResponseWriter"/>
+<p/>
+</li>
+ <li>The update request parameter to choose Update Request Processor Chain is
+renamed from "update.processor" to "update.chain". The old parameter was
+deprecated but still working since Solr3.2, but is now removed
+entirely.
+<p/>
+</li>
+ <li>The <indexDefaults> and <mainIndex> sections of solrconfig.xml are discontinued
+and replaced with the <indexConfig> section. There are also better defaults.
+When migrating, if you don't know what your old settings mean, simply delete
+both <indexDefaults> and <mainIndex> sections. If you have customizations,
+put them in <indexConfig> section - with same syntax as before.
+<p/>
+</li>
+ <li>Two of the SolrServer subclasses in SolrJ were renamed/replaced.
+CommonsHttpSolrServer is now HttpSolrServer, and
+StreamingUpdateSolrServer is now ConcurrentUpdateSolrServer.
+<p/>
+</li>
+ <li>The PingRequestHandler no longer looks for a <healthcheck/> option in the
+(legacy) <admin> section of solrconfig.xml. Users who wish to take
+advantage of this feature should configure a "healthcheckFile" init param
+directly on the PingRequestHandler. As part of this change, relative file
+paths have been fixed to be resolved against the data dir. See the example
+solrconfig.xml and <a href="http://issues.apache.org/jira/browse/SOLR-1258">SOLR-1258</a> for more details.
+<p/>
+</li>
+ <li>Due to low level changes to support SolrCloud, the uniqueKey field can no
+longer be populated via <copyField/> or <field default=...> in the
+schema.xml. Users wishing to have Solr automatically generate a uniqueKey
+value when adding documents should instead use an instance of
+solr.UUIDUpdateProcessorFactory in their update processor chain. See
+<a href="http://issues.apache.org/jira/browse/SOLR-2796">SOLR-2796</a> for more details.
