### 1. 创建测试索引 ###

--------------------

PUT test
    {
      "mappings": {
        "test1": {
          "properties": {
            "num1": {
              "type": "integer"
            },
            "num2": {
              "type": "integer"
            },
            "num3": {
              "type": "nested",
              "properties": {
                "num31": {
                  "type": "integer"
                },
                "num32": {
                  "type": "integer"
                }
              }
            }
          }
        }
      }
    }

### 2. 添加测试数据 ###

--------------------

PUT test/test1/1
    {
      "num1": 11,
      "num2": 12,
      "num3": [
        {
          "num31": 131,
          "num32": 132
        },
        {
          "num31": 133,
          "num32": 134
        }
      ]
    }
    
    PUT test/test1/2
    {
      "num1": 21,
      "num2": 12,
      "num3": [
        {
          "num31": 231,
          "num32": 232
        },
        {
          "num31": 233,
          "num32": 234
        }
      ]
    }

### 3. 查看数据 ###

--------------------

GET test/test1/_search

### 4. 根据id更新数据 ###

--------------------

POST test/test1/1/_update
    {
      "doc": {
        "num1": 10
      }
    }

### 5. 使用 update\_by\_query 更新数据 ###

--------------------

POST test/test1/_update_by_query
    {
      "script": {
        "lang": "painless",
        "source": "ctx._source.num1=111;ctx._source.num2=222"
      },
      "query": {
        "bool": {
          "must": [
            {
              "term": {
                "num2": {
                  "value": "12"
                }
              } 
            } 
          ]
        }
      }
    }

### 6. 使用 update\_by\_query 为 nested 类型追加单条数据 ###

--------------------

POST test/test1/_update_by_query
    {
      "script": {
        "lang": "painless",
        "source": "ctx._source.num3.add(params.new_data)",
        "params": {
          "new_data": {
            "num31":1111,
            "num32":2222
          }
        }
      },
      "query": {
        "bool": {
          "must": [
            {
              "term": {
                "num2": {
                  "value": "22"
                }
              } 
            } 
          ]
        }
      }
    }

### 7. 使用 update\_by\_query 为 nested 类型追加多条数据 ###

--------------------

POST test/test1/_update_by_query
    {
      "script": {
        "lang": "painless",
        "source": "ctx._source.num3.addAll(params.new_datas)",
        "params": {
          "new_datas": [
            {
              "num31":1111,
              "num32":2222
            },
            {
              "num31":3333,
              "num32":4444
            },
            {
              "num31":5555,
              "num32":6666
            }
          ]
        }
      },
      "query": {
        "bool": {
          "must": [
            {
              "term": {
                "num2": {
                  "value": "12"
                }
              } 
            } 
          ]
