什么是Elasticsearch-py等效于别名操作？

elasticsearch

我正在尝试使用elasticsearch-dsl实现倍数索引方法。基本上有两个步骤：

1.创建别名：

PUT /tweets_1/_alias/tweets_search 
PUT /tweets_1/_alias/tweets_index

2.必要时更改别名：

POST /_aliases
{
  "actions": [
    { "add":    { "index": "tweets_2", "alias": "tweets_search" }}, 
    { "remove": { "index": "tweets_1", "alias": "tweets_index"  }}, 
    { "add":    { "index": "tweets_2", "alias": "tweets_index"  }}  
  ]
}

我只能使用elasticsearch-py（而不是dsl）实现步骤1 ：

from elasticsearch.client import IndicesClient
IndicesClient(client).("tweets_1", "tweets_search")
IndicesClient(client).("tweets_1", "tweets_index")

我不知道在第二步该怎么做。那么，elasticsearch-dsl（或至少在elasticsearch-py中）的等效值是什么？

要实现，您需要使用elasticsearch-py：

from elasticsearch import Elasticsearch
es = Elasticsearch()

# use es.indices instead of instantiating IndicesClient
es.indices.put_alias(index='tweets_1', name='tweets_search')
es.indices.put_alias(index='tweets_1', name='tweets_index')

es.indices.update_aliases({
  "actions": [
    { "add":    { "index": "tweets_2", "alias": "tweets_search" }}, 
    { "remove": { "index": "tweets_1", "alias": "tweets_index"  }}, 
    { "add":    { "index": "tweets_2", "alias": "tweets_index"  }}  
  ]
})
