Pravděpodobně neexistují žádné dobré způsoby, jak to udělat, pouze ručně:
Object[] r = (Object[]) em.createNativeQuery(
"select id,title,shorttitle,datestamp,body,true as published, ts_headline(body,q,'ShortWord=0') as headline, type from articles,to_tsquery('english',?) as q where idxfti @@ q order by ts_rank(idxfti,q) desc","ArticleWithHeadline")
.setParameter(...).getSingleResult();
Article a = (Article) r[0];
a.setHeadline((String) r[1]);

@Entity
@SqlResultSetMapping(
name = "ArticleWithHeadline",
entities = @EntityResult(entityClass = Article.class),
columns = @ColumnResult(name = "HEADLINE"))
public class Article {
@Transient
private String headline;
...
}
