How to change the order of search results groups?

Autocomplete suggestions are divided into groups. For example, product category results appear above products. How to change this?

1. Create a new fibosearch.php file in the root directory of your child theme
2. Paste the following code into this file:

<?php

/** -------------------------------------
 *  Custom autocomplete headlines order
 *  ------------------------------------- */
add_filter( 'dgwt/wcas/search_groups', function ( $groups ) {

  $groups['tax_brand']['order']           = 5;
  $groups['tax_product_cat']['order'] = 120;
  $groups['tax_product_tag']['order'] = 20;
  $groups['post']['order']            = 30;
  $groups['page']['order']            = 40;
  $groups['product']['order']         = 100;

  return $groups;
} );

3. Change the priorities. If you want to display products under categories, change $groups['product']['order'] = 100; to $groups['product']['order'] = 3;
