> 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
> <pre></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>
> </pre>
> What do you think about that ?
> Ps: sorry for english write, i am a french guy.
