The same question as I have posted to SO: http://stackoverflow.com/questions/16143167/hibernate-search-search-from-any-indexed-entity ...
I am using Hibernate-search for searching data in my Jboss application. I have 3 JPA entity classes that all extend BaseEntity class and each are indexed by Lucene. For example:
Code:
@MappedSuperclass
public abstract class BaseEntity implements Serializable {
@Temporal(TemporalType.TIMESTAMP)
private Date created;
public abstract Long getId();
}
@Entity
@Table(name = "DVD")
public class Dvd extends BaseEntity {
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private Long id;
@Field
private String title;
}
@Entity
@Table(name = "BOOK")
public class Book extends BaseEntity {
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private Long id;
@Field
private String author;
}
Now I would like to search for either DVD title or Book author by wildcard search query and get the result list as List. This is what I have this far:
Code:
public List<BaseEntity> search(String query, int firstResult, int maxResults) {
List<BaseEntity> results = null;
FullTextEntityManager fullTextEntityManager = Search.getFullTextEntityManager(em);
Query luceneQuery = new WildcardQuery(new Term("*", "*" + query + "*"));
FullTextQuery fullTextQuery = fullTextEntityManager.createFullTextQuery(luceneQuery, BaseEntity.class);
fullTextQuery.setFirstResult(firstResult);
fullTextQuery.setMaxResults(maxResults);
results = fullTextQuery.getResultList();
return results;
}
But with this I am not getting any results. How is it possible to get this to work or is there even way without using buildQueryBuilder for each entity? Thanks!
