Search not working for custom post type

We use a standard custom post type (see the code below). The plugin does not find any of these posts. I added the CPT in the settings and activated search for CPTs. Am I missing anything?

function shopify_cpt()
{
    $labels = array(
        'name'                  => 'Shopify Produkte',
        'singular_name'         => 'Shopify',
        'menu_name'             => 'Shopify',
        'all_items'             => 'Alle Produkte',
        'add_new'               => 'Neues Produkt'
   );
    $args = array(
        'labels'                => $labels,
        'public'                => true,
        'publicly_queryable'    => true,
        'show_ui'               => true,
        'show_in_menu'          => true,
        'query_var'             => true,
        'menu_icon'             => 'dashicons-format-gallery',
        'show_in_admin_bar'     => false,
        'can_export'            => true,
        'rewrite'               => array('slug' => 'bilder'),
        'capability_type'       => 'post',
        'has_archive'           => true,
        'hierarchical'          => false,
        'menu_position'         => 1,
        'exclude_from_search'   => false,
        'taxonomies'            => array('category', 'post_tag'),
        'supports'              => array('title', 'editor', 'author', 'thumbnail', 'excerpt', 'revisions'),
   );
    register_post_type('shopify', $args);
}
add_action('init', 'shopify_cpt');
