查看所有索引

GET _cat/indices

– 创建索引

PUT /demo_test
{
  "settings": {
    "number_of_shards": 2,
    "number_of_replicas": 1
  }
}

– 指定索引新增字段

PUT /demo_test/_mapping/
{
      "properties":{
      "sku_id":{
        "type":"long"
      },
      "sku_name":{
        "type":"keyword"
      },
      "sku_picture_url":{
        "type":"keyword"
      },
      "address":{
        "type":"text",
		"analyzer": "ik_max_word"
      },
       "createTime" : {
            "type" : "date",
            "format" : "yyyy-MM-dd HH:mm:ss"
      }
    }
  
 }

也可以同时置顶 settings、mappings

PUT /demo_test/
{
  "settings": {
    "number_of_shards": 2,
    "number_of_replicas": 2
  },
  "mappings": {
    
    "properties":{
      "sku_id":{
        "type":"long"
      },
      "sku_name":{
        "type":"keyword"
      },
      "sku_picture_url":{
        "type":"keyword"
      },
      "address":{
        "type":"text",
		"analyzer": "ik_max_word"
      },
       "createTime" : {
            "type" : "date",
            "format" : "yyyy-MM-dd HH:mm:ss"
      }
    }
    
  } 
  
 }

通过 script 给指定字段赋值（一般新增地段后给字段赋默认值）

POST /demo_test/_update_by_query
{
  "script": {
    "source": "if (doc['createTime'] == null) {doc['createTime'] = '2022-07-03 00:00:00'}",
    "lang": "painless"
  }
}
