Hardy Ferentschik updated HSEARCH-115:
--------------------------------------

    Description: 
Hi,

Null elements are not indexed by lucene then it's not easy to use a nullable property in lucene query.
I have a TagTranslation entity in my model with a nullable property language. In this case null is used as default language for tag translation.
Each translation may have many variations like synonyms. 

Because I can specified a default value for null value in the @Field annotation like this @Field(index=Index.UN_TOKENIZED, store=Store.NO, default='null'), i can't search a cat tag with a default translation like this : +value:cat* +lang:null 

{code}
@Entity()
@Table(name="indexing_tag_trans")
@org.hibernate.annotations.Cache(usage=org.hibernate.annotations.CacheConcurrencyStrategy.READ_WRITE)
@Indexed
public class TagTranslation implements java.io.Serializable {
    
  
	private static final long serialVersionUID = -1065316566731456110L;
	
    @Id
    @GeneratedValue(strategy=GenerationType.IDENTITY)
    @DocumentId
    private Integer id;
    
	@Field(index=Index.UN_TOKENIZED, store=Store.NO)
    private String language;
    
    @Field(index=Index.TOKENIZED, store=Store.YES)
    private String value;
    
    @OneToMany(cascade=CascadeType.ALL, fetch=FetchType.LAZY)
    @org.hibernate.annotations.Fetch(org.hibernate.annotations.FetchMode.SUBSELECT)
    @JoinColumn(name="translation_id")
    @IndexedEmbedded
    private List<TagVariation> variations = new LinkedList<TagVariation>();

    
    public TagTranslation() { }
...
{code}

What do you think about that ?

Ps: sorry for english write, i am a french guy.
