I want to use hibernate search,through netbeans for search by keyword on my database.Using Lucene I am able to search through 1 table but as I have multiple tables,I need to search on them also.Kindly Help me..as I am new to Lucene I am not able to manipulate the indexes or its search techniques.

Here is the sample of code:
package beans.search;
import java.io.IOException;
import java.io.StringReader;
import org.apache.lucene.document.Field;
import org.apache.lucene.document.Document;

import org.apache.lucene.analysis.TokenStream;
import org.apache.lucene.analysis.standard.StandardAnalyzer;
import org.apache.lucene.index.IndexWriter;
//import org.apache.lucene.index.MultiSearcher;
import beans.business.Jobdetails;
import java.util.List;
import manager.JobManager;

//import org.apache.lucene.util.Version;
//import org.apache.lucene.index.IndexWriterConfig;
import org.apache.lucene.analysis.Analyzer;
/**
*
*/
public class Indexer {
/** Creates a new instance of Indexer */
public Indexer() {
System.out.println("I am in indexer()");
}


//StandardAnalyzer analyzer = new StandardAnalyzer(Version.LUCENE_40);

private IndexWriter indexWriter = null;

//IndexWriterConfig indexWriterConfig = new IndexWriterConfig(Version.LUCENE_40);

//IndexWriterConfig indexWriterConfig = new IndexWriterConfig(Version.LUCENE_40);

public IndexWriter getIndexWriter(boolean create) throws IOException {
//System.out.println("I am in getWriter()");
if (indexWriter == null) {
indexWriter = new IndexWriter("index-directory",new StandardAnalyzer(),create);
System.out.println("index-directory created");
}
return indexWriter;
}

public void closeIndexWriter() throws IOException {
System.out.println("I am in closeIndexWriter()");
if (indexWriter != null) {
indexWriter.close();
}
}

public void indexHotel(Jobdetails jobdetails) throws IOException {
//System.out.println("I am in indexHotel()");

//System.out.println("Indexing hotel: " + jobdetails);
IndexWriter writer = getIndexWriter(false);
Document doc = new Document();

// doc.add(new Field("id", hotel.getId(), Field.Store.YES, Field.Index.NO));
//doc.add(new Field("jobcode", jobdetails.getJobcode(), Field.Store.YES, Field.Index.TOKENIZED));
doc.add(new Field("jobtitle", jobdetails.getJobtitle(), Field.Store.YES, Field.Index.UN_TOKENIZED));
doc.add(new Field("jobtype", jobdetails.getJobtype(), Field.Store.YES, Field.Index.TOKENIZED));
String fullSearchableText = jobdetails.getJobcode() + " " + jobdetails.getJobtitle() + " " +jobdetails.getJobtype() ;
doc.add(new Field("content", fullSearchableText, Field.Store.NO, Field.Index.TOKENIZED));
writer.addDocument(doc);
}

public void rebuildIndexes() throws IOException {
//
// Erase existing index
//
//System.out.println("I am in rebuildIndexes()");
getIndexWriter(true);
//
// Index all Accommodation entries
//
//indexHotel(hotel);
List<Jobdetails> allJobs = new JobManager().getAllJobs();

for (int i=0;i<allJobs.size();i++)
{
Jobdetails jobdetails = allJobs.get(i);
indexHotel(jobdetails);
}



//
// Don't forget to close the index writer when done
//
closeIndexWriter();
}
}
For tracing the compiler I have Used statements like I am in closewriter()..etc

Thanks in advance.

What is your actual problem and question? If you are new to Hibernate Search why do you not start with the "Getting started" section of the documentation - http://docs.jboss.org/hibernate/stable/search/reference/en-US/html_single/#getting-started?
