     [[1]] add the jackrabbit-text-extractors jar file and the dependencies
           defined in the Maven POM in the Jackrabbit classpath, and

     [[2]] add the fully qualified class names listed above in the
           "textFilterClasses" parameter of the "SearchIndex" configuration
           element of a Jackrabbit workspace configuration file
           (workspace.xml).
