在具有共享属性的2个子类上使用Hibernate搜索

我有以下数据模型：

@Entity
@Inheritance(strategy = InheritanceType.TABLE_PER_CLASS)
public abstract class AbstractRecord
    implements Serializable
{
    ...
    @Id
    @GeneratedValue(strategy = GenerationType.TABLE)
    @Column(name = "id", nullable = false)
    @DocumentId
    private Integer id;
    ...

}

} 如您所见，EntryDetail和EntryDetailCtx共享相同的属性receiverName，我在通过以下代码搜索值（如IndividualName1）时遇到问题：

@Stateless
@TransactionAttribute(TransactionAttributeType.MANDATORY)
@RolesAllowed({PermissionUtil.SEARCH_LIST,
    PermissionUtil.LUCENE_INDEX
})
public class SearchFacade
{
    ...
    @RolesAllowed(PermissionUtil.SEARCH_LIST)
    @TransactionAttribute(TransactionAttributeType.REQUIRED)
    public List<AbstractRecord> doSearch(String stringToFind)
    {
        List<AbstractRecord> result = null;

        // Test Search for specific values of an Abstract Record
        // Aim to return the number of retreived results
        EntityManager em = emf.createEntityManager();
        FullTextEntityManager fullTextEntityManager =
            org.hibernate.search.jpa.Search.getFullTextEntityManager(em);
        String[] fields =
            // Fields to be reviewed
            new String[]
            {   ....,"receiverName",.... 
            };

        //Create a multi-field Lucene query
        StandardAnalyzer stdAnalyzer = new StandardAnalyzer(Version.LUCENE_30);
        MultiFieldQueryParser parser =
            new MultiFieldQueryParser(Version.LUCENE_30, fields, stdAnalyzer);
        org.apache.lucene.search.Query query = null;

        try
        {
            query = parser.parse(stringToFind);
        }
        catch (ParseException ex)
        {
            Logger.getLogger(SearchFacade.class.getName()).log(Level.SEVERE, null, ex);
        }

        long time1 = System.currentTimeMillis();

        // Wrap Lucene query in a javax.persistence.Query
        javax.persistence.Query persistenceQuery =
            fullTextEntityManager.createFullTextQuery(query);
        // Execute search
        //HAVING PROBLEMS HERE
        result = (List<AbstractRecord>) persistenceQuery.getResultList();

        long time2 = System.currentTimeMillis();
        Logger.getLogger(SearchFacade.class.getName())
              .log(
            Level.FINER, "Hibernate Search Execution time: {0}",
            Long.toString(time2 - time1));

        //em.getTransaction().commit();
        em.close();

        return result;
    }

我已经通读了很多hibernate搜索论坛，甚至hibernate search in Action书籍，但没有任何积极的结果，有人能给我一些想法或可能的解决方案吗？ 谢谢

编辑：发现问题在于EntryDetail和EntryDetailCtx都可以具有相同的ID，因为它们位于不同的表上。。但是，由于从AbstractRecord继承的@documentID在搜索执行时可以在两个表中重复，因此会产生问题。。。现在我还有一个问题，它是：

@Entity
@Inheritance(strategy = InheritanceType.TABLE_PER_CLASS)
public abstract class AbstractRecord
    implements Serializable
{
    //~ Instance variables ---------------------------------------------------------------
/** SERIALID */ public static final String SERIALID = "hyzmfgSwl5hsDbxZIitNILMT2/eiPYJErJcqIMun3/PVy3SbbiQie4k9lLnL450BhwL8EnUMyc+wrhgZtUBTdG9/YUuJ+ni/FRAdRGzTy7UrQI7opbrYRYehDUwj3hg9";
    /** id for this record. */
    @Id
    @GeneratedValue(strategy = GenerationType.TABLE)
    @Column(name = "id", nullable = false)
    private Integer id;

    /** line number for this record. */
    @Field(index=Index.UN_TOKENIZED, store=Store.NO)
    @Column(name = "record_number", nullable = false)
    private Integer recordNumber;

    /** record types for this record. */
    @Field(index=Index.UN_TOKENIZED, store=Store.NO)
    @Column(name = "record_type", nullable = false)
    private Integer recordType;

    /** Current status for this record. */
    @Field(index=Index.UN_TOKENIZED, store=Store.NO)
    @Column(name = "record_status", nullable = false)
    @Enumerated(EnumType.ORDINAL)
    private RecordStatus recordStatus;

    /** unique table key for the file. */
    @Field(index=Index.UN_TOKENIZED, store=Store.NO)
    @Column(name = "unique_table_key", nullable = false)
    private String uniqueTableKey;

    ...
}

我需要uniqueTableKey和recordNumber作为搜索的新@documentID，但是Hibernate搜索只允许1个documentID，帮助？

此问题的可能解决方案如下： 和

然后将上述选择的任何解决方案注释为@DocumentId
