以上是html部分，下面是php部分
public function getsearch(){
//这个方法是表单点击搜索时action提交的方法
$client = ClientBuilder::create()->build();
$keys = Request::instance()->param('keyword');
$keys = $keys ? $keys : '测试';
$params = [
'index' => 'article_index',
'type' => 'article_type',
'body' => [
'query' => [
'match' => [
'content' => $keys
]
]
]
];
$response = $client->search($params);
$str = '';
$list = $response['hits']['hits'];
//pp($list);die;
$str .= '<script src="https://cdn.staticfile.org/jquery/1.10.2/jquery.min.js"></script>

}

return $str;
}
public function search() {
//这部分方法是ajax 在搜索框输入文字时进行提示的方法
/*$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();
$keys = Request::instance()->param('keyword');//tp5方法，获取get post数据自动辨别
$keys = $keys ? $keys : '6';

}
最终效果
