// Add search bar to the top of the sidebar
function add_search_bar_to_sidebar() {
    ?>
    <div class="custom-sidebar-search">
        <?php get_search_form(); ?>
    </div>
    <?php
}
add_action('generate_before_sidebar_content', 'add_search_bar_to_sidebar');

This code uses the get_search_form() function to output the default search form in WordPress. It then adds this search form to a custom div with the class custom-sidebar-search. You can customize the styling of this search bar by adding CSS to your theme.

Remember to test this code in a safe environment before applying it to your live website. Additionally, make sure you have a backup of your theme files or use a child theme to avoid losing your changes during theme updates.
