Setting post type to true in functions.php

Hi,

I am trying to use

By returning true or false you can turn search filtering respectively.

Example: Let’s say you need to disable search filtering if searching by specific post_type. In this case you could add following code to you functions.php:

add_filter(‘searchexclude_filter_search’, ‘filterForProducts’, 10, 2);
function filterForProducts($exclude, $query)
{
return $exclude && ‘attachment‘ !== $query->get(‘post_type’);
}

I am not a programmer… it does not work somehow… how do I set to ‘true’?

??
