CodeIgniter route does not work

Hello, 

I am working on old CodeIgniter 2 project I added a new route to application/config/routes.php 

here is the new file:

$route['products'] = 'products/index';$route['product/(:num)'] = 'products/single/$1';$route['(:any)'] = 'pages/$1';$route['product/(:any)'] = 'products/search/$1';$route['default_controller'] = "home";$route['404_override'] = '';

the request does not go to Products class, it returns 404 not found 

Here is my controller:

<?phpclass Products extends CI_Controller { public function index() { #### Some Code #### } public function single($id) { #### Some Code #### } public function search($text) { #### Some Code #### }}

Any help,

Thanks
