public abstract class Association
extends CompoundSelector

Associations are Selectors which associate other Selectors with an Operation Example use of Associations Conjunction and Disjunction

  Query query = queryService.createQuery(Content.class);
  Disjunction or = new Disjunction();
  or.add(Selectors.nameLike("news%"));
  Conjunction and = new Conjunction();
  and.add(Selectors.nameLike("article%"));
  and.add(ProfileSelectors.keywordsContain("news"));
  or.add(and);
  query.addSelector(or);
