How can I remove the search window?

Question

How can I remove the search window? I have searched and tried everything to no avail. The theme I'm using is BlankSlate.

The search window (top-right) doesn't appear when logged-out, but I'd still like to get rid of it if I can.

I searched through all the files in the theme for the word "search" and tried removing that command from entry.php and entry-summary.php. None of that had an effect. I also tried removing the search.php file, that had no effect. I also tried adding:

form.search-form { display: none; }

Into the style.css page. Also no change.

To save you grief, any edits to the core files provided by WordPress will potentially break your website if you modify it incorrectly. Also with each new update provided by WordPress, it will overwrite and re-add the files to their default/updated state.

To hide the search, add the following to your child theme's function.php:

add_action( 'wp_before_admin_bar_render', 'wpse_254662_toolbar', 10, 1 );

function wpse_254662_toolbar() {
    # Hide search from admin toolbar
    global $wp_admin_bar;
    $wp_admin_bar -> remove_menu( 'search' );
}
