Using Restrictions class, we can narrow the result of our query.Here are some restrictions that can also be use to narrow our Criteria query result.

* Restrictions.ne("title", "Twist and Shout") - Apply a "not equal" constraint to the named property.
* Restrictions.ilike("title", "Twist%") - A case-insensitive "like".
* Restrictions.isNull("title") - Apply an "is null" constraint to the named property.
* Restrictions.gt("duration", new Integer(200)) - Apply a "greater than" constraint to the named property.
* Restrictions.between("duration", new Integer(100), new Integer(200)) - Apply a "between" constraint to the named property
* Restrictions.or(criterionA, criterionB) - Return the disjuction of two expressions.
* Restrictions.disjuction() - Group expressions together in a single disjunction.
