public class LuceneUpdateService
extends Object
implements UpdateService

The LuceneUpdateService provides methods to write Imixs Workitems into a Lucene search index. With the method addWorkitem() a ItemCollection can be added to a lucene search index. The service init method reads the property file 'imixs.properties' from the current classpath to determine the configuration.

• The property "IndexDir" defines the location of the lucene index
• The property "FulltextFieldList" lists all fields which should be searchable after a workitem was updated
• The property "IndexFieldList" lists all fields which should be indexed as keywords by the lucene search engine

The singleton pattern is used to avoid conflicts within multi-thread scenarios. The service is used by the LucenPlugin to update the lucene index during a workflow processing step.
