使用Elastic Search通过@ keyword与multi_match进行搜索

Question

我正在尝试搜索@ keyword不工作的电子邮件地址。能帮帮我吗？

$max_file_upload = 10;


if (isset($_FILES['uploadfile']['name'])) {
      $num = count($_FILES['uploadfile']['name']);
      if ($num > $max_file_upload){
      $errormsg = "HTTPS PROCESS: - File limit is Over";
      return $message;
      exit;
      }
    }
