Starting with version 1.9, the default search index implementation in JCR allows you to control which properties of a node are indexed. You also can define different analyzers for different nodes.

The configuration parameter is called indexingConfiguration and per default is not set. This means all properties of a node are indexed.

If you wish to configure the indexing behavior, you need to add a parameter to the query-handler element in your configuration file.

<param name="indexing-configuration-path" value="/indexing_configuration.xml"/>
