Elasticsearch-PHP基础用法

/引入es搜索类
//require './vendor/autoload.php';
use Elasticsearch\ClientBuilder;

class Index
{
    public function index()
    {

        /*$client = ClientBuilder::create()->setHosts($hosts)->build();*/
        //实例化es类；在项目中引入自动加载文件，并且实例化一个客户端：
       $client = ClientBuilder::create()->build();
        try {
               //将文档加入索引
               $data = db::name('articles')->select();
               //查询出多条数据添加索引
               foreach ($data as $k => $v) {
                     $params = [
                          'index' => 'article_index',
