Help needed to implement pagination

I started using codeigniter a few days ago, I've read the "Pagination in Codeigniter with Step by Step Example" by guru99, but I'm having a hard time understanding how to add pagination to the code that I have.

There is someone who can help me with this? I am willing to pay if necessary

This is my code

* as my pagination does not work, my search shows the last 100 entries
(see line $obj_result = $this->resume_model->get_searched_resume($param, 100, 0);

Every help is welcome. Thanks

PHP Code:

<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Resume_search extends CI_Controller {

public function __construct(){
        parent::__construct();
$this->ads = '';
$this->ads = $this->ads_model->get_ads();
    }

public function index()
{
$data['ads_row'] = $this->ads;
if($_POST){
$this->search();
}

$param = str_replace('-',' ', $this->uri->segment(2));
$param = strip_tags($param);
$data['msg'] = '';

$total_rows = $this->resume_model->count_searched_resume_records($param);
$obj_result = $this->resume_model->get_searched_resume($param, 100, 0);

//Left Side Starts
//$left_side_array = $this->left_side_data($param);
//Left Side Ends

$current_records = ($this->uri->segment(3)) ? $this->uri->segment(3)*20 : 20;
$current_records = ($current_records>$total_rows)?$total_rows:$current_records;
$data['total_rows'] = $total_rows;
$data['page'] = $current_records;
$data['from_record'] = 1;
$data['result'] = $obj_result;
$data['param'] = $param;
$data['url_param'] = $this->uri->segment(2);
/*$data['left_side_title'] = $left_side_array['title_group'];
$data['left_side_city'] = $left_side_array['city_group'];
$data['left_side_company'] = $left_side_array['company_group'];
$data['left_side_salary_range'] = $left_side_array['salary_range_group'];*/
$data['title'] = 'Paga Title' ;
$this->load->view('resume_search_view',$data);
}

public function search()
{
$this->form_validation->set_rules('resume_params', 'keywords', 'trim|required');
if ($this->form_validation->run() === FALSE) {
redirect(base_url('resume_search'),'');
return;
}

$job_param = $this->input->post('resume_params');

$string1 = preg_replace('/[^a-zA-Z0-9 ]/s', '', $job_param);
$param = strtolower(preg_replace('/\s+/', '-', $string1));

redirect(base_url('busca/'.$param),'');

}
