This is my config:

Code:
$this->pagination->initialize(

 array_merge(

  $this->config->item('pagination'),

  array(

   'total_rows' => $this->_data['contents']['total'],

   'per_page' => AUDIO_PER_PAGE

  )

 )

);

config pagination (in config.php):

Code:
$config['pagination'] = array( 

    'page_query_string' => TRUE,

    'query_string_segment' => 'page',

    'full_tag_open' => '<div id="pagination">',

    'full_tag_close' => '</div>',

    'anchor_class' => 'class="number" ',

    'cur_tag_open' => '<a class="number current">',

    'cur_tag_close' => '</a>',

    'next_link' => '&raquo;',

    'prev_link' => '&laquo;',

    'use_page_numbers' => TRUE,

    'num_links' => 4,

);

And i have link: http://domain.com/manager.html It's work well.
But when link is: http://domain.com/search.html?q=anh It's generate the pagination links become http://domain.com/search.html?page=1 , it's remove q param. How to config it's work well?
