Hidden woocommerce products still showing up in search results

I’m really new to php editing but I’m trying to learn. My woocommerce products that are set to “hidden” under catalog visibility are still showing up under search results. How do I keep hidden products out of my search results? I found this thread and tried adding the below code mentioned at the bottom of the thread (I’m using Woocommerce 3.2.1) to my child theme’s functions.php file. It gave me the white screen of death and this error: Parse error: syntax error, unexpected ‘=>’ (T_DOUBLE_ARROW). Based on some google searches, it seems this woocommerce functionality was recently changed from a meta query to a tax query in the 3.0 release so a lot of the documentation out there seems to be out of date. The previously mentioned thread is the most current I could find. Appreciate help in what I’m doing wrong. Thanks!

<?php
/*
Code to remove hidden woocommerce products from being displayed in a site search
*/
'tax_query' => array(
                  array(
                        'taxonomy' => 'product_visibility',
                        'field'    => 'name',
                        'terms'    => 'exclude-from-catalog',
                        'operator' => 'NOT IN',

                  )
              ) 

Here is my system status page:
