      I’m sure you’ve found this answer but for reference:
      to do multiple you have to decide if you’re going to use and AND or OR qualifier, then you can add multiple arrays:

      $args = array(
    'meta_query' => array(
        'relation' => 'OR',
        array(
            'key'     => '_product_attributes',
            'value'   => $serialized_value_1,
            'compare' => 'LIKE',
        ),
        array(
            'key'     => '_product_attributes',
            'value'   => $serialized_value_2,
            'compare' => 'LIKE',
        ),
    )
);
