The "UpdateRequestProcessor" page has been changed by AlessandroBenedetti:
https://wiki.apache.org/solr/UpdateRequestProcessor?action=diff&rev1=18&rev2=19

  [[https://issues.apache.org/jira/browse/SOLR-1725|SOLR-1725]], to be committed for Solr 4.0 final release, adds a ScriptUpdateProcessor.  There is a StatelessScriptUpdateProcessorFactory included to configure into your solrconfig.xml configuration file.  The ScriptUpdateProcessor allows for Java scripting engines to be used during the Solr document update processing, allowing dramatic flexibility in expressing custom document processing before being indexed.  (it also allows hooks to commit, delete, etc, but add will have the most common usage).  More coming soon!
  
  = Full list of UpdateRequestProcessor Factories =
- The nearly-complete list of the factories can be found by looking at the Javadoc for [[http://lucene.apache.org/solr/api/org/apache/solr/update/processor/UpdateRequestProcessorFactory.html|UpdateRequestProcessorFactory]] and navigating through the various children and grand-children subclasses. Notice that it will only show children classes in the *solr-core* group. This does not include factories that come from other modules, such as [[http://lucene.apache.org/solr/4_7_1/solr-uima/org/apache/solr/uima/processor/UIMAUpdateRequestProcessorFactory.html|UIMAUpdateRequestProcessorFactory]]
