[Hibernate Search] Indexing

Hello,

I'm still learning how to make Hibernate Search work.

First, I want to know how I must use FullTextSession.index because I believed that there was an automatic indexing.

This is a part of my cfg.xml :

Code:

        <property name="hibernate.search.default.directory_provider">org.hibernate.search.store.FSDirectoryProvider</property>
        <property name="hibernate.search.default.indexBase">/home/fmn/templucene/test</property>

        <mapping resource="servicedonnees/Mapping.hbm.xml" />

      <event type="post-update">
         <listener class="org.hibernate.search.event.FullTextIndexEventListener"/>
      </event>
      <event type="post-insert">
         <listener class="org.hibernate.search.event.FullTextIndexEventListener"/>
      </event>
      <event type="post-delete">
         <listener class="org.hibernate.search.event.FullTextIndexEventListener"/>
      </event>

And my code is :

Code:

      Session s = HibernateUtil.getCurrentSession();
      FullTextSession fullTextSession = Search.createFullTextSession(s);   

      Video video1 = new Video("titre 1", 30);
      Video video2 = new Video("titre 2", 50); 
      Video video3 = new Video("titre 8", 60);
      
      s.persist(video1);
      s.persist(video2);
      s.persist(video3);
      
      fullTextSession.index(video1);
      fullTextSession.index(video2);
      fullTextSession.index(video3);
      
      QueryParser parser = new QueryParser("title", new StopAnalyzer() );

      org.apache.lucene.search.Query luceneQuery = null;
      try {
         luceneQuery = parser.parse("titre:t*");
      } catch (ParseException e) {
         e.printStackTrace();
      }
      org.hibernate.Query fullTextQuery = fullTextSession.createFullTextQuery(luceneQuery);

      List result = (fullTextQuery).list(); //return a list of managed objects
      Iterator i = result.iterator();
      while(i.hasNext())
      {
         System.out.println("Res : "+i.next());
      }

It works, but is it possible not to use index() ?

I answer to my question : I forgot to open a transaction and then to commit :

Code:

      Transaction tx = s.beginTransaction();

      Video video1 = new Video("titre 1", 30);
      Video video2 = new Video("titre 2", 50); 
      Video video3 = new Video("titre 8", 60);
      
      s.persist(video1);
      s.persist(video2);
      s.persist(video3);

      tx.commit();

just to clarify, this is not required to manually call index, that would be lame ;-)
