Pagination Issue in CodeIgniter

Question

I'm facing an issue with the pagination in my system. Pagination is working fine here.

But if I'm searching something in that text field and if the result is more than 5 ($config['per_page'] = 5;) its not showing the pagination buttons.

And actually, I have 6 results for the search keyword 'shihas'.

And also I can see the 6th result once I go to www.example.com/path/2 .

But still, the pagination link is not there. Please tell me a solution for this issue.
Controller:

public function index()
    {

        //all the posts sent by the view       
        $search_string = $this->input->post('search_string');        
        $order = $this->input->post('order'); 
        $order_type = $this->input->post('order_type'); 

        //pagination settings
        $config['per_page'] = 5;
        $config['base_url'] = base_url().'admin/posts';
