When I open up my index with Luke, I can query on the subjectDN field with the string "subjectdn1", and get 10+ results back. When I do it in code... I don't get anything back. I think I'm missing something.
Code:
  @Test
  public void searchForUsers() throws Exception {
     ftem = Search.getFullTextEntityManager(em);  // em is initialized in setup()

     QueryBuilder qb = ftem.getSearchFactory().buildQueryBuilder().forEntity(JPAUser.class).get();

     org.apache.lucene.search.Query qry = qb.keyword().onField("subjectDN").matching("subjectdn1").createQuery();

     javax.persistence.Query JPAftq = ftem.createFullTextQuery(qry, JPAUser.class);
    
     List<?> result = JPAftq.getResultList();

     System.out.println(result.toString());
     if(result.isEmpty())
        System.out.println("empty result set");
     else
        System.out.println("non-empty result set");
  }

output is:
[]
empty result set

I THINK the above code is properly setup. I have a feeling my mistake may lay in my JPAUser class:
Code:
@Indexed(index = "fulltext")
@Entity
@Table(name = "USER")
public class JPAUser extends User implements java.io.Serializable {

  // there are no global variables
  // left out constructors for the sake of space

  @Override
  @DocumentId
  @Id
  @Column(name = "user_id")
  @GeneratedValue(strategy = GenerationType.SEQUENCE)
  public long getUserId() {
    return super.getUserId();
  }

  @Override
  public void setUserId(long userId) {
    super.setUserId(userId);
  }

  @Override
  @Field(analyze = Analyze.YES, index = Index.YES, store = Store.YES)
  @Boost(value=2.0f)
  public String getEmail() {
    return super.getEmail();
  }

  @Override
  public void setEmail(String email) {
    super.setEmail(email);
  }

  @Override
  @Field(analyze = Analyze.YES, index = Index.YES, store = Store.YES)
  public String getSubjectDN() {
    return super.getSubjectDN();
  }

  @Override
  public void setSubjectDN(String subjectDN) {
    super.setSubjectDN(subjectDN);
  }
}

I'm not convinced I have this annotated properly.


Anyways, any ideas why I'm not getting anything?
Thanks.

Hi,

is the example you are given an actual example of your data? Using the approach you have shown the standard analyzer will be applied on your search string "subjectdn1" and the resulting tokens used in a term query. Is this what you want? And are you using the same type of query in Luke? Or are you maybe using wildcard search there?
Also remember the values you see in Luke are the field values as is (store = Store.YES), not the actual searchable tokens. Have you tried adding '.ignoreAnalyzer()' between onField() and matching().
This are only some tips. It all depends how EXACTLY your values look like, but in most cases where people mentioned a mismatch between Lucke and a fulltext query, the problem was that in fact not the same query was applied (think analyzer here).
