How to restrict the search fields for a specific post type

I figured it out, thanks

function my_search_pre_get_posts($query)
{

    if($query->query_vars['s'] != '' && is_search())
    {

        if(absint($query->query_vars['s']))
        {
            $query->set('p', $query->query_vars['s']);
            $query->set('post_type', ['property']);
            // Reset the search value
            $query->set('s', '');
        }
    }
}

// Filter the search page
add_filter('pre_get_posts', 'my_search_pre_get_posts');

A very good learning of WordPress functionality.
