}
}

这是弹性搜索中搜索的示例json响应。我们需要在所有json对象中添加一个键值对（“spec”：“4gb”），例如，

"_source": {
      "id": "01",
      "type": "product" ,
      "spec": "4gb"
    },
"_source": {
      "id": "02",
      "type": "product" ,
      "spec": "4gb"
    }

此更新应该在一个命令中。请指导我们执行此操作。

Answer 1

看看Update By Query API。您可以准备a query to match all documents并使用scripting添加所需的媒体资源。

示例：

POST twitter/_update_by_query
{
  "script": {
    "source": "ctx._source.likes++",
    "lang": "painless"
  },
  "query": {
    "term": {
      "user": "kimchy"
    }
  }
}

Answer 2

尝试

POST /surtest1/_update_by_query?refresh
{
"script": {
    "source": "ctx._source['spec']='4gb'"
 }
}

使用新的键值对更新弹性搜索数据
