How do you "OR" criteria together when using a criteria query with hibernate?

    //Expression :  (c1 AND c2) OR (c3)      


     Criteria criteria = session.createCriteria(Employee.class);

      Criterion c1 = Restrictions.like("name", "%e%");
      Criterion c2 = Restrictions.ge("salary", 10000.00);
      Criterion c3 = Restrictions.like("name", "%YYY%");
      Criterion c4 = Restrictions.or(Restrictions.and(c1, c2), c3);
      criteria.add(c4);

//Same thing can be done for (c1 OR c2) AND c3, or any complex expression.

//Expression :  (c1 AND c2) OR (c3)      


 Criteria criteria = session.createCriteria(Employee.class);

  Criterion c1 = Restrictions.like("name", "%e%");
  Criterion c2 = Restrictions.ge("salary", 10000.00);
  Criterion c3 = Restrictions.like("name", "%YYY%");
  Criterion c4 = Restrictions.or(Restrictions.and(c1, c2), c3);
  criteria.add(c4);

  //Same thing can be done for (c1 OR c2) AND c3, or any complex expression.

You want to use Restrictions.disjuntion(). Like so

session.createCriteria(Whatever.class)
    .add(Restrictions.disjunction()
        .add(Restrictions.eq("name", queryString))
        .add(Restrictions.eq("address", queryString))
        .add(Restrictions.eq("phoneNumber", queryString))
    );

See the Hibernate doc here.

Assuming you have a hibernate session to hand then something like the following should work:

Criteria c = session.createCriteria(Whatever.class);
Disjunction or = Restrictions.disjunction();
or.add(Restrictions.eq("name",searchString));
or.add(Restrictions.eq("address",searchString));
or.add(Restrictions.eq("phoneNumber",searchString));
c.add(or);
