i have the following classes

@Entity
@Inheritance(strategy = InheritanceType.JOINED)
public class GenericContent {String columnA ...}

@Entity
public class AContent extends GenericContent {String columnB ...}
@Entity
public class BContent extends GenericContent {String columnB ...}
@Entity
public class CContent extends GenericContent { String columnC}

i want to search in columnA for all the 3 classes. which is simpel
criteria = getSessionFactory().getCurrentSession().createCriteria(GenericContent .class);
disjunction.add(Restrictions.ilike("columnA", "foo", MatchMode.ANYWHERE));
criteria.add(disjunction);
List<GenericContent> results = criteria.list();

now i want to add a filter for all columnB's. but this is not in the genericContent. and i rather not go by all subclasses one by one.

is there a solution?


ps all pseudocode

i now use compass (or elasticsearch) for this
