即使搜索条件不合格，HibernateCallback也会返回值

Question

我的代码出了问题。如果我输入了正确的标准，那就说300它返回正确的结果数量。但是如果我没有合格的搜索条件，它仍然会返回不正确的结果。

@Override
public Page<ApPayment> searchPayment(final String searchCriteria,
    final PageSetting pageSetting) {
HibernateCallback<Page<ApPayment>> paymentCallBack = new     HibernateCallback<Page<ApPayment>>() {
    @Override
    public Page<ApPayment> doInHibernate(Session session)
            throws HibernateException, SQLException {
        Criteria criteria =  session.createCriteria(ApPayment.class);
        if(!searchCriteria.isEmpty() && StringFormatUtil.isNumeric(searchCriteria)) {

            Integer paymentNo = Integer.valueOf(searchCriteria);
            Double amount = Double.valueOf(searchCriteria);

            criteria.add(Restrictions.or(Restrictions.like(ApPayment.FIELD.paymentNumber.name(), paymentNo), Restrictions.eq(ApPayment.FIELD.amount.name(), amount)));
        }
        Page<ApPayment> payments = getAll(criteria, pageSetting);
        for (ApPayment payment: payments.getData()) {
            --some codes--
        }
        return payments;
     }
  };
  return getHibernateTemplate().execute(paymentCallBack);
}

提前致谢。
