Make a number range filter in change list

[yillkid]

Hi all, I want to add a filter in my change list,
user can input maximum and minimum number,
after press ok button, template will render output data in change list.

There is my model.py :

class test(models.Model):
    odd_even = models.DecimalField(max_digits = 2, decimal_places = 2)

I have already read the Django document, and still don't know how to do that.
Can anyone give me a hint ?
