Relationship between tables causes the error: "Unknown column 'Setores.name' in 'where clause'"

I have a relationship between 2 models : Ramais and Setores , and print the data from the 2 on the screen, but I need to make a Search field work, but I was only able to search the table data of Ramais , like name and extension, data of Setores I can not pull from the bank, does anyone have any clue what I am doing wrong?

public function search()
{
    $ramais = $this->paginate($this->Ramais);

    if ($this->request->is('post')) {
        $search = null;
        if (isset($this->request->data['search'])) {
            $search = $this->request->data['search'];
        }

        $ramal = $this->Ramais->find('all',
            [
                'contain' => ['Setores'],

                'conditions'=>['OR'=>
                    [
                        'Ramais.name LIKE'=>'%'.$search.'%',
                        'Ramais.ramal LIKE'=>'%'.$search.'%',
                        'Setores.name LIKE'=>'%'.$search.'%'
                    ]
                ]
            ]
        );

        //debug($ramal); exit();

        $this->set(compact('ramais', 'ramal', 'setor'));
        $this->set('_serialize', ['ramais'], ['setor']);
        $this->render('index');

    }
}

It brings the following error :

  

Error: SQLSTATE[42S22]: Column not found: 1054 Unknown column 'Setores.name' in 'where clause'
