1 前言

一个问题，一篇文章，一出故事。
笔者需要测试部署的Elasticsearch生产环境，于是官方文档一顿查找，找到以下测试方法。O(∩_∩)O哈哈~

2 最佳实践

2.1 操作环境

如果你尚未部署Elasticsearch与Kibana环境，请参阅如下文档部署，

如何部署Docker Kibana?

2.2 最佳实践

2.2.1 插入数据

使用如下连接登录Kibana并选择【dev_tools】工具，
http://docker01.cmdschool.org:5601/
窗口显示如下，

2.2.2 插入数据

PUT hockey/_bulk?refresh

{"index":{"_id":2}}
{"first":"sean","last":"monohan","goals":[7,54,26],"assists":[11,26,13],"gp":[26,82,82],"born":"1994/10/12"}

2.2.3 查询数据

GET hockey/_search
{
  "query": {
    "function_score": {
      "script_score": {
        "script": {
          "lang": "painless",
          "source": """
            int total = 0;
            for (int i = 0; i < doc['goals'].length; ++i) {
              total += doc['goals'][i];
            }
            return total;
          """
        }
      }
    }
  }
}
