如何在弹性搜索python中将不同的字段值相加并存储在另一个字段中(弹性搜索字段操作)

{
  "name": "John",
  "age": 25,
  "salary": 5000
}
{
  "name": "Jane",
  "age": 30,
  "salary": 7000
}

from elasticsearch import Elasticsearch

# 连接到Elasticsearch
es = Elasticsearch()

# 定义脚本
script = {
  "source": "ctx._source.total = ctx._source.age + ctx._source.salary"
}

# 更新文档
es.update(index="my_index", id="1", body={"script": script})

# 检索文档
result = es.get(index="my_index", id="1")

# 打印结果
print(result["_source"])

{
  "name": "John",
  "age": 25,
  "salary": 5000,
  "total": 5025
}
