Codeigniter: Pagination wont show up - codeigniter

Question

First of all I'm a newbie of Codeigniter.
I'm having problems in showing the pagination links. But when i use search the pagination shows up. Then another problem pops up, when i search there will be links of pagination, when I click the links it doesnt show the paginated search but show the whole non search results.
Controller:
public function info($offset=0)
{
$this->load->library('pagination');
$count = $this->ticketing_mdl->count_all_ticket();
$limit = 4;
$config['base_url'] = "/ticketing/index.php/ticketing/info";
$config['total_rows'] = $count;
$config['per_page'] = $limit;
$config['num_links'] = $limit;
$this->pagination->initialize($config);
$page = ($this->uri->segment(3)) ? $this->uri->segment(3) : 0;
$data['pagination'] = $this->pagination->create_links();
$data['ticket_list'] = $this->ticketing_mdl->get_all_ticket($limit, $offset);
$this->load->view('ticketing/header');
$this->load->view('ticketing/left_menu');
$this->load->view('ticketing/info',$data);
}
Model:
function get_all_ticket($limit,$page)
{
if($this->input->get('search')){
$match = $this->input->get("search");
$sql = "SELECT * FROM db_ticketing.tr_ticket WHERE requested_by LIKE '%$match%' limit $page,$limit";
return $this->db->query($sql);
}else{
$match = $this->input->get("search");
//$sql = "SELECT * FROM db_contract.bs_contract WHERE contract_tag LIKE '%$match%'";
$sql = "SELECT * FROM db_ticketing.tr_ticket limit $page";
return $this->db->query($sql);
}
}

Answer 1

Change:
return $this->db->query($sql); to
return $this->db->query($sql)->result();
Hope this help!

Fixed my first problem with showing the pagination. now the problem is when i search a keyword the pagination shows up. but when i click the pagination links it does not continues the search result pagination
Controller
if($this->input->get('search')){
$count = $this->ticketing_mdl->count_all_ticket();
$config['total_rows'] = $count;
}else{
$this->db->where('is_valid','1');
$config['total_rows'] = $this->db->count_all_results('db_ticketing.tr_ticket');
}
