如何在elasticsearch中更新时间戳的范围？

from datetime import datetime
from elasticsearch import Elasticsearch

# 创建Elasticsearch客户端
es = Elasticsearch()

# 索引和文档类型
index = "your_index"
doc_type = "your_doc_type"

# 查询时间范围
start_time = datetime(2022, 1, 1)  # 起始时间
end_time = datetime(2022, 1, 31)   # 结束时间

# 构建查询条件
query = {
    "query": {
        "range": {
            "timestamp_field": {
                "gte": start_time,
                "lte": end_time
            }
        }
    }
}

# 查询满足条件的文档
result = es.search(index=index, doc_type=doc_type, body=query)

# 获取文档列表
docs = result["hits"]["hits"]

# 更新文档的时间戳字段
for doc in docs:
    doc_id = doc["_id"]
    new_timestamp = datetime.now()
    
    # 构建更新请求
    update_body = {
        "doc": {
            "timestamp_field": new_timestamp
        }
    }
    
    # 更新文档
    es.update(index=index, doc_type=doc_type, id=doc_id, body=update_body)
