constraint to limit the objects returned upon query execution .
Constraints are constructed by calling Query.constrain() .
Constraints can be joined with the methods and() and or() .
The methods to modify the constraint evaluation algorithm may be merged, to construct combined evaluation rules. Examples:
Constraint#smaller().equal()for "smaller or equal"
Constraint#not().like()for "not like"
Constraint#not().greater().equal()for "not greater or equal"
