8.8. Alias management 別名管理

8.8.1. 查看索引別名

沒有設置任何別名將返回下面的資料結構

# curl -XGET http://localhost:9200/_aliases?pretty
{
  "information_v1" : {
    "aliases" : { }
  },
  "information_v2" : {
    "aliases" : { }
  }
}
			

information 是 information_v1 的別名

# curl -XGET http://localhost:9200/_aliases?pretty
{
  "information_v1" : {
    "aliases" : {
      "information" : { }
    }
  },
  "information_v2" : {
    "aliases" : { }
  }
}
			

8.8.2. 創建索引別名

curl -XPUT http://localhost:9200/information_v1
curl -XPOST http://localhost:9200/information_v1/news/_mapping?pretty -d'
{
    "news": {
            "_all": {
            "analyzer": "ik_max_word",
            "search_analyzer": "ik_max_word",
            "term_vector": "no",
            "store": "false"
        	},
		"properties": {
			"title": {
                "type": "string",
                "store": "no",
                "term_vector": "with_positions_offsets",
                "analyzer": "ik_max_word",
                "search_analyzer": "ik_max_word",
                "include_in_all": "true",
                "boost": 8
			},
			"content": {
                "type": "string",
                "store": "no",
                "term_vector": "with_positions_offsets",
                "analyzer": "ik_max_word",
                "search_analyzer": "ik_max_word",
                "include_in_all": "true",
                "boost": 8
			},
			"tag": {
                "type": "string",
                "store": "no",
                "term_vector": "with_positions_offsets",
                "analyzer": "ik_max_word",
                "search_analyzer": "ik_max_word",
                "include_in_all": "true",
                "boost": 8
            },
            "ctime": { 
				"type": "date"
		    }
        }
    }
}'	
			
curl -XPOST http://localhost:9200/_aliases -d '
{
    "actions": [
        { "add": {
            "alias": "information",
            "index": "information_v1"
        }}
    ]
}
