Codeigniter parentheses in dynamic Active Record query

Question

I\'m producing a query like the following using ActiveRecord

SELECT * FROM (`foods`) WHERE `type` = \'fruits\' AND 
       `tags` LIKE \'%green%\' OR `tags`

In the CI 3.0-dev you can add groups in query:

$this->db->select('id, title')
->group_start()
->or_like([ 'title' => $s, 'id' => $s ])
->group_end()                
->where([ 'b_del' => 0 ]);

Produces:

SELECT `id`, `title`, `venda1`
FROM `itens`
WHERE   
(
`title` LIKE '%a%' ESCAPE '!'
OR  `id` LIKE '%a%' ESCAPE '!'
 )
AND `b_del` =0
