两种分词器使用的最佳实践 🍻

索引时用ik_max_word，在搜索时用ik_smart。
   { "arttitle": {
            "type": "text",
            "analyzer": "ik_max_word",
            "search_analyzer": "ik_smart"
         }
     }

字段禁止动态添加映射

"dynamic" :"strict",

日期动态格式化

"dynamic_date_formats":"yyyy-MM-dd HH:mm:ss||yyyy-MM-dd||epoch_millis",

别名

• 别名添加
  POST _aliases
  {
  "actions" : [{"add" : {"index" : "student" , "alias" : "in1"}}]
  }

• 别名删除
  POST /_aliases
  {
  "actions": [
  {"remove": {"index": "school", "alias": "in1"}}
  ]
  }

• 别名修改
  POST _aliases
  {
  "actions" : [{"remove" : {"index" : "student" , "alias" : "in1"}}],
  "actions" : [{"add" : {"index" : "student" , "alias" : "in2"}}]
  }
