specific pages

Hello!

Can the search engine show specific pages?

I have seen this code on the web, but it is only for categories. Could it be done so that it shows only those added there?

add_filter('dgwt/wcas/search/product_cat/args', function ($args){
    $args['exclude'] = array(999, 1000, 1001); // The ID of categories to exclude
    return $args;
});

Thank you!
