[hibernate-dev] problem in implementing the hibernate search

[nitin warkar]

Hi all,

I am struggling with the hibernate search, I had been implemented a small
POC on the hibernate search.It works perfectly for my one database table
named as "Item" but when I am trying to use the same configuration for some
other tables then Session.createFullTextQuery(luceneQuery, Item.class);
returns me null result.

I have configure the beans and hibernate configure same as I had used it for
the Item table.

Please help me ASAP trying from last two days.

See the code below....
======================searcher.java file code===============================

*Code:*
String[] productFields = { "name_astp", "description_astp" }; // targeted
fields
   //   Map<String, Float> boostPerField = new HashMap<String, Float>(2); //
boost
                                                         // factors
   //   boostPerField.put("name_astp", (float) 4);
   //   boostPerField.put("description_astp", (float) 1);
      // QueryParser parser = new MultiFieldQueryParser(productFields,new
      // StandardAnalyzer(),boostPerField);
      //QueryParser parser = new QueryParser("name_astp", new
StandardAnalyzer());

      QueryParser parser = new MultiFieldQueryParser(productFields,
            new StandardAnalyzer());
      org.apache.lucene.search.Query luceneQuery;
      try {
         luceneQuery = parser.parse(seachKeyStr);
      } catch (ParseException e) {
         throw new RuntimeException("Unable to parse query: " + seachKeyStr,
               e);
      }
      Session session =
HibernateUtil.getSessionFactory().getCurrentSession();

      session.beginTransaction();
      FullTextSession ftSession =
org.hibernate.search.Search.createFullTextSession(session);


      // ftSession=org.hibernate.search.Search.getFullTextSession(session);

      Query query = ftSession.createFullTextQuery(luceneQuery); // return,
Item.class

      @SuppressWarnings("unchecked")
      List<Item> results = null;
      try {
         results = query.list();
      } catch (Exception ex) {
         ex.printStackTrace();
      }


//======================Item.hbm.xml============================================

*Code:*
<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC
   "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
   "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">

       <id name="id">
          <generator class="native"/>
       </id>
       <property name="name_astp"/>
       <property name="description_ast"/>
   </class>
</hibernate-mapping>


//============================= hibernate.cfg.xml

*Code:*

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate

    <property

    <property

    <!-- classes mapping -->
    <mapping class="com.manning.hsia.dvdstore.model.Item"/>
  </session-factory>
</hibernate-configuration>



hope you will get clear idea about what exactly I am trying to do........

Thank you in advance.
