Elasticsearch索引模板和別名

創建模板(模板名和索引名一樣都不能有大寫)

PUT http://222.108.x.x:9200/_template/templateds

{
    "template": "dsideal*",
    "order": 0,
    "settings": {
        "number_of_shards": 5
    },
    "aliases": {
        "dsideal-query": {}　　　　　　#起個別名
    },
    "mappings": {
        "doc": {
            "properties": {
                "person_name": {
                    "type": "keyword"
                },
                "gender_id": {
                    "type": "long"
                },
                "bureau_id": {
                    "type": "long"
                }
            }
        }
    }
}

寫一些數據

POST http://222.108.x.x:9200/dsideal10/doc/1

{
    "person_name": "張三",
    "gender_id": 1,
    "bureau_id": 2
}

POST http://222.108.x.x:9200/dsideal11/doc/2

{
    "person_name": "李四",
    "gender_id": 2,
    "bureau_id": 2
}

 會按照模板自動生成兩個索引“dsideal10”和“dsideal11”

 

可以利用在創建模板時起的別名進行查詢

POST http://222.108.x.x:9200/dsideal-query/_search

{
    "size": 10,
    "query": {
        "bool": {
            "must": [
                {
                    "term": {
                        "bureau_id": "2"
                    }
                }
            ]
        }
    }
}

 

創建多個索引別名【備忘】

POST http://222.108.x.x:9200/_aliases

{
    "actions" : [
        { "add" : { "index" : "dsideal1","alias" : "alias1" } },
        { "add" : { "index" : "dsideal2","alias" : "alias1" } }
    ]
}

 

在創建一個索引時可為這個索引根據條件創建多個別名

POST http://222.108.x.x:9200/test100

{
    "aliases" : {
        "2014" : {
            "filter" : {
                "term" : {"year": 2014 }
            }
        },
        "2015" : {
            "filter" : {
                "term" : {"year": 2015 }
            }
        },
        "2016" : {
            "filter" : {
                "term" : {"year": 2016 }
            }
        }
    },
    "mappings": {
        "doc": {
            "properties": {
                "person_name": {
                    "type": "keyword"
                },
                "year": {
                    "type": "long"
                },
                "bureau_id": {
                    "type": "long"
                }
            }
        }
    }
}

說明：當插入year=2015的數據時可用2015這個別名去查詢

測試插入一些數據

{"person_name":"張三","year":2014,"bureau_id":2},
{"person_name":"李四","year":2015,"bureau_id":3},
{"person_name":"王五","year":2015,"bureau_id":3},
{"person_name":"趙六","year":2016,"bureau_id":4}

 post http://222.108.x.x:9200/2015/_search

{
    "size": 10,
    "query": {
        "bool": {
            "must": [
                {
                    "match_all": {
                        
                    }
                }
            ]
        }
    }
}

就只返回year=2015的數據
