Codeigniter pagination displays extra num links -

when search pages in categories displays result of pages in category.

for testing have set limit per page 1 on search_for function.

question/problem: if there 2 pages show in result reason pagination links display 5 links should display 2 pagination links.

functions model on controller testing.

i think problem lies db->like , db->or_like in model. why display 5 pagination links when should display 2 if 2 results found.

controller

<?php  class category_search extends catalog_controller {      public function __construct() {         parent::__construct();     }      public function index() {         $data['title'] = "search category";          $data['categories'] = array();          $results = $this->get_categories();          foreach ($results $result) {             $data['categories'][] = array(                 'category_id' => $result['category_id'],                 'name' => $result['name']             );         }          $this->load->library('form_validation');          $this->form_validation->set_rules('page', 'category');         $this->form_validation->set_rules('name', 'name');          if ($this->form_validation->run() == false) {              $this->load->view('theme/default/template/pages/search_category_view', $data);          } else {              redirect('pages/category_search/search_for' .

i suppose 5 table rows no where/like filter , come function count everything:

public function get_total_pages() {     return $this->db->count_all($this->db->dbprefix . 'page'); } 

here should add same clause.
