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 its default value 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.
<property name="indexing-configuration-path" value="/indexing_configuration.xml"/>
Index configuration path can indicate any file located on the file system, in the jar or war files.
You have to declare the namespace prefixes in the configuration element that you are using throughout the .xml file.
