在创建索引模板的同时，可以加入别名的控制

1 创建索引模板


DELETE _index_template/student_template_001
POST _index_template/student_template_001
{
  "index_patterns": [
    "student-*"
  ],
  "template": {
    "settings": {
      "number_of_shards": 3
    },
    "mappings": {
      "properties": {
        "id": {
          "type": "long"
        },
        "name": {
          "type": "text",
          "fields": {
            "key": {
              "type": "keyword"
            }
          }
        },
        "year": {
          "type": "integer",
          "fields": {
            "key": {
              "type": "keyword"
            }
          }
        }
      }
    },
    "aliases": {
      "student": {
        "filter": {
          "term": {
            "year": "1"
          }
        }
      }
    }
  }
}

在 aliases 中设置了 student 别名，并且在别名中设置了 filter。

2 添加数据



PUT student-001/_doc/1?routing=1
{
  "id": 1,
  "name": "student-a",
  "year": 1
}

PUT student-001/_doc/2?routing=2
{
  "id": 2,
  "name": "student-b",
  "year": 2
}

PUT student-001/_doc/3?routing=3
{
  "id": 3,
  "name": "student-c",
  "year": 3
}
PUT student-001/_doc/4?routing=3
{
  "id": 4,
  "name": "student-c",
  "year": 1
}

PUT student-001/_alias/student_route_1
{
  "routing": "1"
}

PUT student-001/_alias/student_year_1
{
  "filter": {
    "term": {
      "year": "1"
    }
  }
}

3 查询数据

GET student/_search

可以成功查询出 "year": 1 的数据，查询结果：

{
  "took" : 2,
  "timed_out" : false,
  "_shards" : {
    "total" : 3,
    "successful" : 3,
    "skipped" : 0,
    "failed" : 0
  },
  "hits" : {
    "total" : {
      "value" : 3,
      "relation" : "eq"
    },
    "max_score" : 1.0,
    "hits" : [
      {
        "_index" : "student-001",
        "_type" : "_doc",
        "_id" : "6-nnM3gB_jopoKW0Srd_",
        "_score" : 1.0,
        "_source" : {
          "id" : 5,
          "name" : "student-5",
          "year" : 1
        }
      },
      {
        "_index" : "student-001",
        "_type" : "_doc",
        "_id" : "4",
        "_score" : 1.0,
        "_routing" : "3",
        "_source" : {
          "id" : 4,
          "name" : "student-c",
          "year" : 1
        }
      },
      {
        "_index" : "student-001",
        "_type" : "_doc",
        "_id" : "1",
        "_score" : 1.0,
        "_routing" : "1",
        "_source" : {
          "id" : 1,
          "name" : "student-a",
          "year" : 1
        }
      }
    ]
  }
}
