meta_query, how to search using both relation OR & AND?

I found the solution with some help.
The code below worked perfectly.

    $args => array(
        'relation' => 'AND',
        array(
            'relation' => 'OR',
            array(
                'key' => 'title',
                'value' => $searchvalue,
                'compare' => 'LIKE'
            ),
            array(
                'key' => 'author',
                'value' => $searchvalue,
                'compare' => 'LIKE'
            ),
            array(
                'key' => 'genre',
                'value' => $searchvalue,
                'compare' => 'LIKE'
            )
        ),
        array(
            'key' => 'rating',
            'value' => $ratingvalue,
            'compare' => '=',
            'type' => 'NUMERIC'

        )
    )
);
