    <p>I had a question now, this one regarding lucene. I was trying to make a lucene source code that can do indexing and store them first in a memory using RAMDirectory and then flush this index in a memory into a disk using FSDirectory. I had done some modifications of this code but to no avail. maybe some of you can help me out a bit.</p> <p>so what's the best way for me to integrate RAMDirectory in this source code before putting them in FSDirectory. any help would be appreciated though here is the source code.</p> <pre><code>import org.apache.lucene.analysis.SimpleAnalyzer; import org.apache.lucene.document.Document; import org.apache.lucene.document.Field; import org.apache.lucene.index.IndexWriter; import org.apache.lucene.store.FSDirectory; import java.io.File; import java.io.FileReader; import java.io.IOException; public class SimpleFileIndexer { public static void main(String[] args) throws Exception { File indexDir = new File("C:/Users/Raden/Documents/lucene/LuceneHibernate/adi"); File dataDir = new File("C:/Users/Raden/Documents/lucene/LuceneHibernate/adi"); String suffix = "txt"; SimpleFileIndexer indexer = new SimpleFileIndexer(); int numIndex = indexer.index(indexDir, dataDir, suffix); System.out.println("Total files indexed " + numIndex); } private int index(File indexDir, File dataDir, String suffix) throws Exception { IndexWriter indexWriter = new IndexWriter( FSDirectory.open(indexDir), new SimpleAnalyzer(), true, IndexWriter.MaxFieldLength.LIMITED); indexWriter.setUseCompoundFile(false); indexDirectory(indexWriter, dataDir, suffix); int numIndexed = indexWriter.maxDoc(); indexWriter.optimize(); indexWriter.close(); return numIndexed; } private void indexDirectory(IndexWriter indexWriter, File dataDir, String suffix) throws IOException { File[] files = dataDir.listFiles(); for (int i = 0; i &lt; files.length; i++) { File f = files[i]; if (f.isDirectory()) { indexDirectory(indexWriter, f, suffix); } else { indexFileWithIndexWriter(indexWriter, f, suffix); } } } private void indexFileWithIndexWriter(IndexWriter indexWriter, File f, String suffix) throws IOException { if (f.isHidden() || f.isDirectory() || !f.canRead() || !f.exists()) { return; } if (suffix != null &amp;&amp; !f.getName().endsWith(suffix)) { return; } System.out.println("Indexing file " + f.getCanonicalPath()); Document doc = new Document(); doc.add(new Field("contents", new FileReader(f))); doc.add(new Field("filename", f.getCanonicalPath(), Field.Store.YES, Field.Index.ANALYZED)); indexWriter.addDocument(doc); } } </code></pre>

    1. COSuggestion: add the lucene tag to your question. There is a number of knowledgeable Lucene developers in StackOverflow and they will find your question if you tag it properly.

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.
