CodeIgniter pagination not working for get method -

i needed pagination parameters. in method i've written following code follows.

public function index($offset = 0) {      $data['title_for_layout'] = 'apartment advertisement - search';       // pagination config     $this->load->library('pagination');      $pagination['enable_query_strings'] = true;     $pagination['page_query_string'] = true;     $pagination['allow_get_array'] = true;     $pagination['first_url'] = base_url('search');     $pagination['base_url'] = $config['first_url'];     $pagination['total_rows'] = $this->aa_movies->no_of_search_movies();     $data['no_of_results'] = $pagination['total_rows'];     $pagination['use_page_numbers'] = true;     $pagination['per_page'] = 20;      // initialize pagination     $this->pagination->initialize($pagination);      // offset     $offset = 20 * $offset;      // apartments     $data['apartments'] = $this->aa_movies->search_movies($this->input->get('keyword'), $this->input->get('city'), $this->input->get('locations'), $offset);      $this->load->view($this->config->item('index_search_view'), $data); } 

in view

<?php echo form_open(base_url('search'), array('method' => 'get'); ?> <?php echo $this->pagination->create_links(); ?> <?php echo form_close(); ?> 

so pagination url looks like

http://localhost/reelstubs/search/1 

but wanted in pagination url follows

http://localhost/reelstubs/search?keyword=complex&city=bangalore&page=1 

even tried changing pagination base_url including $_server['request_uri']. url looks like

http://localhost/reelstubs/search?keyword=complex&city=bangalore/1 

so i'm not getting page no using $this->uri->segment(); please me on this. been 2 days i've wasted on this. work more appreciated.

1. you can add filtering string (keyword , city) in hidden inputs , values using $this->input->get('name')

2. or can send necessary values in segment , using $this->uri->segment();

   http://localhost/search/method(func)/complex/bangalore/1

   $keyword = $this->uri->segment('3');
   $city = $this->uri->segment('4');
   $page = $this->uri->segment('5');
