Hello.

I'm a newbie in Jackrabbit.

I'm trying to index some content of different types of documents (word, pdf, xml, ...).

I've configured the searchIndex in my workspace.xml in this way:

<SearchIndex class="org.apache.jackrabbit.core.query.lucene.SearchIndex">
            <param name="path" value="${wsp.home}/index"/>
            <param name="supportHighlighting" value="true"/>
                                               <param name="textFilterClasses" value="org.apache.jackrabbit.extractor.MsWordTextExtractor,

        </SearchIndex>


When I create a document in the repository, I add the content in this way:

contenido = nodo.addNode("jcr:content", "nt:resource");
                  contenido.setProperty("jcr:data", J_OperacionesSesion
                             .getValueFactory().createBinary(is));

                  MimetypesFileTypeMap mimetypes = new MimetypesFileTypeMap();
                  String mime = mimetypes.getContentType(nodo.getName());
                  contenido.setProperty("jcr:mimeType", "application/pdf");

Afer creating the document, this warning is thrown:

16.12.2010 13:03:32 *WARN * LazyTextExtractorField: Failed to extract text from a binary property

Later, when I search for the document, filtering by content, in this way:

String consulta = "SELECT * FROM [arch:documento] AS documento WHERE CONTAINS ( documento.*,
'ubicacion')"; (arch:document extends from nt:file)

No documents were found.


Can you help me please??.


Thanks and regards.
