在Prestashop中更改搜索方法

搜索功能如下所示,3个字符后匹配结果并输入,它们与产品名称或描述匹配。我希望在Prestashop 1.7中MegaShop主题的搜索功能有如下变化:

搜索应该能够找到单词的各个部分。例如,如果用户写“hi-he”,搜索应该能够找到“high-hees”。这应该也适用于其他顺序,比如说“hi-hi”(而不是“hi-he”)也会返回“highheels”和其他每一篇用不同单词匹配这些词的文章。

在/root/modules/tptnsearch文件中“tptnsearch ajax php包含:

    <?php

require_once('../../config/config.inc.php');
require_once('../../init.php');
require_once(dirname(__FILE__).'/tptnsearch.php');

$tptnsearch = new TptnSearch();
$result_products = array();
$products = array();
$tptnsearch_key = Tools::getValue('search_key');
$context = Context::getContext();
$count = 0;
$product_link = $context->link;

if (Tools::strlen($tptnsearch_key) >= 3) {
    $products = Product::searchByName($context->language->id, $tptnsearch_key);
    $total_products = count($products);
    if ($total_products) {
        for ($i = 0; $i < $total_products; $i++) {
            if (($products[$i]['name']) && ($products[$i]['active'])) {
                $images = Image::getImages($context->language->id, $products[$i]['id_product']);
                $product = new Product($products[$i]['id_product']);
                $products[$i]['link'] = $product_link->getProductLink($products[$i]['id_product'], $product->link_rewrite[1], $product->id_category_default, $product->ean13);
                $products[$i]['link_rewrite'] = $product->link_rewrite[1];
                $products[$i]['id_image'] = $images[0]['id_image'];
                $products[$i]['price'] = Tools::displayPrice(Tools::convertPrice($products[$i]['price_tax_incl'], $context->currency), $context->currency);
                if ($count < Configuration::get('TPTN_SEARCH_COUNT')) {
                    $result_products[] = $products[$i];
                    $count ++;
                } else {
                    break;
                }
            }
        }
    }

    $context->smarty->assign(array(
        'enable_image' => Configuration::get('TPTN_SEARCH_IMAGE'),

        'enable_name' => Configuration::get('TPTN_SEARCH_NAME'),
        'search_alert' => $tptnsearch->no_product,
        'link' => $context->link,
        'products' => $result_products,
    ));

    $context->smarty->display(dirname(__FILE__).'/views/templates/hook/popupsearch.tpl');
} else {
    echo '<div class="wrap_item">'.$tptnsearch->three_character.'</div>';
}
