Solve the following python programming problem given the following code:
@ scenario (prepare_data, cleanup_data) 
def test_post_query_actions(context) : 
    '
    Search with match_all query with post query actions
    ' 
    t = QuerySet ('localhost', index = 'foo') 
    add_document ('foo', { 
        'bar' : 1, 
}) 
    add_document ('foo', { 
        'bar' : 2, 
}) 
    add_document ('foo', { 
        'bar' : 3, 
}) 
    global my_global_var 
    my_global_var = 1 
    def action(self, results, start, stop) : 
        global my_global_var 
        my_global_var += 1 
t.post_query_actions (t) 
    t.order_by (Sort ('bar', order = 'asc')) 
    results = t [0 : 10] 
    len (results).should.equal (3) 
    results [0] ['_source'] ['bar'].should.equal (1) 
    results [1] ['_source'] ['bar'].should.equal (2) 
    results [2] ['_source'] ['bar'].should.equal (3) 
    my_global_var.should.equal (2)
