Lucene只發現幾個匹配

Question

我試圖做一個Domain.class實體的簡單搜索。我有兩個測試。第一個應該創建索引，第二個應該進行實際的搜索。當我運行索引時，它只運行25-30個選擇語句到數據庫。當我做我的搜索測試時，它只獲得13次點擊。它應該在6300點左右。

這是我的代碼：

public class luceneTests { 
    DAOFacade dao = PMF.getTestDAO(); 

    @Test(enabled = false)//only run once to fill the index 
    public void runFirstOnly() throws InterruptedException{ 
     EntityManager em = dao.getEntityManager(); 
     FullTextEntityManager fullTextEntityManager = Search.getFullTextEntityManager(em); 
     fullTextEntityManager.createIndexer(Domain.class).startAndWait(); 
    } 

    @Test(enabled = true) 
    public void simpleSearchTest(){ 

     EntityManager em = dao.getEntityManager(); 
     FullTextEntityManager fullTextEntityManager = 
     org.hibernate.search.jpa.Search.getFullTextEntityManager(em); 
     em.getTransaction().begin(); 

     // create native Lucene query unsing the query DSL 
     // alternatively you can write the Lucene query using the Lucene query parser 
     // or the Lucene programmatic API. The Hibernate Search DSL is recommended though 
     QueryBuilder qb = fullTextEntityManager.getSearchFactory() 
     .buildQueryBuilder().forEntity(Domain.class).get(); 
     org.apache.lucene.search.Query query = qb 
     .keyword().wildcard() 
     .onField("domain") 
//  .andField("state") 
     .matching("domaindom*")  
     .createQuery(); 
     // wrap Lucene query in a javax.persistence.Query 
     javax.persistence.Query persistenceQuery = 
     fullTextEntityManager.createFullTextQuery(query, Domain.class).; 


     // execute search 
     List result = persistenceQuery.setFirstResult(0).setMaxResults(100).getResultList(); 
     System.out.println("SIZE : " +result.size()); 
     for(Object o : result){ 
      if(o instanceof Domain)    
       System.out.println(" Object: "+o + ((Domain)o).getDomainId() + " " + ((Domain)o).getNameservers()); 
     } 
     em.getTransaction().commit(); 
     em.close(); 
    } 
} 

域實體

@Entity 
@Indexed 
@Table(name="Domain", schema="domains") 
@DiscriminatorValue(value="DOMAIN") 
public class Domain implements Serializable { 

    private static final long serialVersionUID = 1L; 

    @Id 
    @Column(name="domainId", nullable=false) 
    public String domainId; 

    @Column(name="domain", nullable=false) 
    @Field(index = Index.UN_TOKENIZED, store= Store.NO) 
    public String domain; 

// there is alot more in this entity but I dont belive its needed. 

做錯了什麼即時通訊有什麼建議？

你如何在DAO中創建你的EntityManager？即

EntityManager em = dao.getEntityManager（）;

也許這EntityManager的不看到之前所做的更改...
