How to use Hibernate Search

How to use hibernate search ?

Below are steps :

1. Add below line above the field declaration which should be indexed
   
   @Field(index=Index.TOKENIZED, store=Store.NO)
   
   
2. In hibernate.cfg.xml, add below property. Path is where index file will be created.
   
   <property name="hibernate.search.default.indexBase">F:\indexes</property>
   
   
3. In hibernate.cfg.xml, add below property after mapping propery.
   
   <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>
   
   
4. Add Indexed annotation on table name on which you want to apply indexing. Over here ItemShop is that table/Entity.
   
   @Entity
   @Indexed
   public class ItemShop
   
   
5. Now run that registry file
   
   AnnotationConfiguration aConf = new AnnotationConfiguration();
   aConf.configure();
   Long t = (Long aConf.buildSessionFactory().openSession().createQuery("select count(*) from ItemShop").uniqueResult();
   System.out.println("starting loop");
   for (int i = 0 ; i< t; i = i+100){
   FullTextSession fullTextSession = Search.createFullTextSession(this.getSession());
   org.hibernate.Transaction tx = fullTextSession.beginTransaction();
   List itemShops = this.getSession().createQuery("from ItemShop").setFirstResult(i).setMaxResults(100).list();
   System.out.println("beginTransaction");
   tx = fullTextSession.beginTransaction();
   for (int j=0;j
   {
   ItemShop itemShop = (ItemShop) itemShops.get(j);
   fullTextSession.index(itemShop);
   Product p = itemShop.getProduct();
   fullTextSession.index(p);
   System.out.println("indexed: "+itemShop.getId());
   }
   tx.commit();
   }
