python - ElasticSearch - python 别名类型

Question

我有一个带有zzz索引和设备文档类型的elasticsearch实例。设备具有不同的制造商:

$ curl 'http://localhost:9200/zzz/devices/_search?pretty=true&q=*:*'

结果:

    ]
  }

如何为 Apple 设备创建别名？我已经尝试过

es.indices.put_alias(index="zzz", name="devices_apple", body={ 
        "routing" : "devices_apple",
        "filter" : {
            "term" : {
                "manufacturer.name" : "Apple"
            }
        }
    });

但是http://localhost:9200/cbp/devices/devices_apple什么也没返回。我对 Elasticsearch 很陌生，所以任何提示都值得赞赏。

Answer 1

试试这个:

es.indices.put_alias(index="zzz", name="devices_apple", body="""{ 
    "routing" : "devices_apple",
    "filter" : {
        "term" : {
            "manufacturer.name" : "Apple"
        }
    }
}""")

您可以保存返回值并打印它。如果它有效，它应该包含“{'acknowledged': True}”。

您还可以在此处查看更改:' http://localhost:9200/zzz '。使用“GET _aliases”请求查看索引上是否有任何新别名。
