Как добавить в функцию поиска «поиск по iD товара»?

Друзья, есть функция которая отвечает за поиск по названию и артикулу, как добавить поиск по id товара?

public function productsAutocomplete($q, $limit = null)
    {
        $limit = $limit !== null ? $limit : $this->limit;

        $product_model = new shopProductModel();
        $q = $product_model->escape($q, 'like');
        $fields = 'id, name AS value, price, count, sku_id';

        $products = $product_model->select($fields)
                                  ->where("name LIKE '$q%'")
                                  ->limit($limit)
                                  ->fetchAll('id');
        $count = count($products);

        if ($count < $limit) {
            $product_skus_model = new shopProductSkusModel();
            $product_ids = $product_skus_model
                ->select('id, product_id')
                ->where("(sku LIKE '$q%' OR name LIKE '$q%')")
                ->limit($limit)
                ->fetchAll('product_id');
            $product_ids = array_keys($product_ids);
            if ($product_ids) {

                                      ->where('id IN ('.implode(',', $product_ids).')')
                                      ->limit($limit - $count)
                                      ->fetchAll('id');
