Well, for some people (like me) that tried to add factory.getCache().evictAll(); and doesn't work, and are used JPA + Hibernate, to refresh a query add the hint org.hibernate.cacheMode to IGNORE. Example:

em.createNamedQuery("SomeEntity.SomeNamedQuery")
  .setHint("org.hibernate.cacheMode", "IGNORE")
  .getResultList();
