Question : Disable for search pages

[JoshuaCrewe]

Menu order for posts is great, except when doing a search where we want most relevant results first.

Is there a way to disable this plugin functionality when just doing a search ?

So far I have got :

function custom_pre_get_posts($wp_query) {
    if( is_admin() || ! $wp_query->is_main_query() ) {
        return;
    }

    if (is_search()) {
        $wp_query->set('orderby', 'relevance');
        $wp_query->set('order', 'DESC');
    }
}

add_action('pre_get_posts', 'custom_pre_get_posts');
