    <p>I wrote (mostly copied from lucene-in-action ebook) an indexing example using Tika. But it doesn't index the documents at all. There is no error on compile or run. I tried indexing a .pdf, .ppt, .doc, even .txt document, no use, at search returns 0 hits, and i payed attention at the words in my documents. Please take a look at the code:</p> <pre><code>public class TikaIndexer extends Indexer { private boolean DEBUG = false; static Set textualMetadataFields = new HashSet(); static { textualMetadataFields.add(Metadata.TITLE); textualMetadataFields.add(Metadata.AUTHOR); textualMetadataFields.add(Metadata.COMMENTS); textualMetadataFields.add(Metadata.KEYWORDS); textualMetadataFields.add(Metadata.DESCRIPTION); textualMetadataFields.add(Metadata.SUBJECT); } public TikaIndexer(String indexDir) throws IOException { super(indexDir); } @Override protected boolean acceptFile(File f) { return true; } @Override protected Document getDocument(File f) throws Exception { Metadata metadata = new Metadata(); metadata.set(Metadata.RESOURCE_NAME_KEY, f.getCanonicalPath()); InputStream is = new FileInputStream(f); Parser parser = new AutoDetectParser(); ContentHandler handler = new BodyContentHandler(10*1024*1024); try { parser.parse(is, handler, metadata, new ParseContext()); } finally { is.close(); } Document doc = new Document(); doc.add(new Field("contents", handler.toString(), Field.Store.NO, Field.Index.ANALYZED)); if (DEBUG) { System.out.println(" intregul textt: " + handler.toString()); } for (String name : metadata.names()) { String value = metadata.get(name); if (textualMetadataFields.contains(name)) { doc.add(new Field("contents", value, Field.Store.NO, Field.Index.ANALYZED)); } doc.add(new Field(name, value, Field.Store.YES, Field.Index.NO)); if (DEBUG) { System.out.println(" " + name + ": " + value); } } if (DEBUG) { System.out.println(); } return doc; } } </code></pre> <p>And main class:</p> <pre><code>public static void main(String args[]) { String indexDir = "src/indexDirectory"; String dataDir = "src/filesDirectory"; try { TikaConfig config = TikaConfig.getDefaultConfig(); List&lt;MediaType&gt; parsers = new ArrayList(config.getParser().getSupportedTypes(new ParseContext())); //3 Collections.sort(parsers); Iterator&lt;MediaType&gt; it = parsers.iterator(); System.out.println(parsers.size()); System.out.println("Tipuri de parsere:"); while (it.hasNext()) { System.out.println(" " + it.next()); } System.out.println(); long start = new Date().getTime(); TikaIndexer indexer = new TikaIndexer(indexDir); int numIndexed = indexer.index(dataDir); long end = new Date().getTime(); System.out.println("Indexarea a " + numIndexed + " fisiere a durat " + (end - start) + " milisecunde."); System.out.println(); System.out.println("--------------------------------------------------------------"); System.out.println(); } catch (Exception ex) { System.out.println("Nu s-a putut realiza indexarea: "); ex.printStackTrace(); Logger.getLogger(Main.class.getName()).log(Level.SEVERE, null, ex); } } </code></pre>

    2. COyou mean, if use only lucene for indexing .txt files? Yes with lucene it works fine, but i need to include other types of docs in my search.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
