ES更新数据

最近项目中用到了ES，有这么一个场景：索引中有个nested结构，要更新nested中的值，如果document没有，需要创建document的，并且要批量，这里的批量指两个：
1，一次更新（upinsert）多个document
2、一次更新nested中的多个值
这是公司一个ES的专家给我写的，特此记录一下：

POST ptp_tags/item/_bulk
{ "update" : { "_id" : "70000004"}, "retry_on_conflict":3 }
{ "script" : { "inline": "ctx._source.object_list.removeIf((item) -> params.objects.stream().anyMatch((object)->object.object_id.equals(item.object_id)) );if (params.deleted != true) {ctx._source.object_list.addAll(params.objects);}", "lang" : "painless", "params" : {"deleted":false, "objects" :  [{"object_id":"p70007","type":1,"object_value":["2005"],"expire_time":1535804643718,"object_value_num":2005.0},{"object_id":"p70008","type":1,"object_value":["2005"],"expire_time":1535804643718,"object_value_num":2006.0}] } }, "upsert":{"product_type":0,"object_list":[{"object_id":"p70007","type":1,"object_value":["2005"],"expire_time":1535804643718,"object_value_num":2005.0},{"object_id":"p70008","type":1,"object_value":["2005"],"expire_time":1535804643718,"object_value_num":2006.0}]}}

如果有多行，可以继续添加。。。。

mapping 结构如下：

"mappings" : {
      "item" : {
        "dynamic" : "false",
        "include_in_all" : false,
        "properties" : {
          "_source_" : {
            "type" : "keyword"
          },
          "id" : {
            "type" : "long"
          },
          "object_list" : {
            "type" : "nested",
            "properties" : {
              "expire_time" : {
                "type" : "date",
                "format" : "yyyy-MM-dd'T'HH:mm:ssZ||yyyy-MM-dd HH:mm:ss||yyyy-MM-dd HH:mm:ss'.0'||yyyy-MM-dd||epoch_millis"
              },
              "object_id" : {
                "type" : "keyword"
              },
              "object_type" : {
                "type" : "keyword"
              },
              "object_value" : {
                "type" : "keyword"
              },
              "object_value_num" : {
                "type" : "double"
              }
            }
          },
          "product_type" : {
            "type" : "keyword"
          }
        }
      }
    }
