Hooks

I’m trying to disable the count value shown in brackets after entries in the Advanced Search fields. Looking through class_hooks_filters.php, I see that there is the below:

function hook_displaycount($c){ return apply_filters(‘hook_displaycount’, $c); }

…would I be right in saying that in my child theme functions.php, I could set this to be 0 rather than the default of 1 which is set in class_search.php? If so, what would be the syntax to do that? 🙂

Thanks,
A
