在elasticsearch文档中有多级字段好吗？

如果是，如何搜索带有嵌套字段的文档

我没有看到关于elasticsearch docshttps的文档：//www.elastic.co/guide/en/elasticsearch/reference/current/index.html

多级I表示嵌套字段

{
 "account_number": 0,
    "balance": 16623,
    "firstname": "Bradshaw",
    "lastname": "Mckenzie",
    "age": 29,
    "gender": "F",
    "address": {
        "244 Columbus Place",
        "employer": "Euron",

        "email": {
            "personal":"[e-mail]",
            "work": "[e-mail]"
        }
        "city": "Hobucken",
        "state": "CO"
    }
}```

In about document address and email inner objects

是的，有多个层次的对象是完全没问题的。

但是，您当前的JSON文档是无效的。我想应该更像这样。

{
    "account_number": 0,
    "balance": 16623,
    "firstname": "Bradshaw",
    "lastname": "Mckenzie",
    "age": 29,
    "gender": "F",
    "address": "244 Columbus Place",
    "employer": "Euron",
    "email": {
        "personal": "[e-mail]",
        "work": "[e-mail]"
    },
    "city": "Hobucken",
    "state": "CO"
}

要访问内部对象，可以使用点表示法。例如：

GET my-index/_search
{
  "query": {
    "match": {
      "email.personal": "[e-mail]"
    }
  }
}
