Confused with "count numbers in the string"

In challenge task 2 of 2, what is the question asking for when it says "return an re.search for exactly count numbers in the string"? I'm not to sure what the question is asking me to do.

import re

def first_number(input_string):
    return re.search(r'\d', input_string)

def numbers(integ, strg):
    return re.search(r'integ', strg)

The question is asking to create a function that takes some integer count and a string. Check to see if there are any number sequences of count digits long. Digits can be test for using \d.

For example, given the input 3 and "this89string123has1stringof3characters", the function should return a search result of "123"
