Lucene index files are empty
I want to umplement full text search using Lucene and Hibernate search. As
I understand, Lucene creats two files. These two files should be contain
some text data, but my index files are empty ( I open these two files with
Luke)
[image: Inline image 1]
here is my code:
@Entity@Indexed@Table(name="Users")@GenericGenerator(name="mongodb_uuidgg",strategy
= "uuid2")public class User implements Serializable{
private static final long serialVersionUID=1L;
@DocumentId
@Id
@GeneratedValue(generator="mongodb_uuidgg")
// @Column(name="id")
@Field(index = Index.YES,analyze = Analyze.YES,store = Store.YES)
private String id;
@Column(name="City")
@Field(index = Index.YES,analyze = Analyze.YES,store = Store.YES)
private String city;
@Column(name="UserID")
@NumericField
@Field(index = Index.YES,analyze = Analyze.NO,store = Store.YES)
private int IdU
and in DAO I have this block of code:
OgmConfiguration cfgogm=new OgmConfiguration();
cfgogm.configure("hibernate.cfg.xml");
serviceregistry=new
ServiceRegistryBuilder().applySettings(cfgogm.getProperties()).buildServiceRegistry();
sessionfactory=cfgogm.buildSessionFactory(serviceregistry);
sessionfactory.openSession();
FullTextSession fulltextsession=
Search.getFullTextSession(sessionfactory.getCurrentSession());
QueryBuilder
querybuilder=fulltextsession.getSearchFactory().buildQueryBuilder().forEntity(User.class).get();
org.apache.lucene.search.Query
lucenequery=querybuilder.keyword().onField("IdU").matching(new
Integer(87709)).createQuery();
org.hibernate.search.FullTextQuery
fulltextquery=fulltextsession.createFullTextQuery(
lucenequery,User.class );
fulltextquery.initializeObjectsWith(ObjectLookupMethod.SKIP,
DatabaseRetrievalMethod.FIND_BY_ID);
List result=fulltextquery.list();
System.out.println(result.size());
could you please say me, what is my mistake?
