elasticsearch官方文档摸索

index

创建索引

PUT google

映射mapping(注意 mapping不能修改)

include_type_name，请求体中是否包含type，高版本中会移除type
Elasticsearc 6.x以后不再支持mapping下多个type，并且 6.x 版本type默认都是 _doc,7.0以后版本将会删除type

PUT /{index} 有type (deprecated)

PUT google/user/_mapping?include_type_name=true
{
  "user": {
    "properties": {
      "name": {
        "type": "text"
      },
      "user_name": {
        "type": "keyword"
      },
      "email": {
        "type": "keyword"
      }
    }
  }
}

PUT /{index} 没type,默认type为_doc

PUT google/_mapping
{
  "properties": {
    "name": {
      "type": "text"
    },
    "user_name": {
