ES如何创建索引

ES如何创建索引 环境

环境：ES 6.8.10
os：Centos 7.8.2003 (Core)

创建索引

1、创建新的索引（index）
PUT indexTest001

2、索引设置
ES 默认提供了好多索引配置选项，参考https://www.elastic.co/guide/en/elasticsearch/reference/5.6/index-modules.html
修改索引设置参考：https://blog.csdn.net/qq_15958689/article/details/79524291

3、创建mapping
先看下刚刚创建的索引的mapping：
GET indextest001/_mapping

由上图显示，新建的索引中，mapping是一个空集，我们要创建这个index的mapping

```xml
POST indextest001/product/_mapping?pretty 

    {"product":{"properties":{"title":{"type":"text","store":"true"},"description":{"type":"text","index":"false"},"price":{"type":"double"},"onSale":{"type":"boolean"},"type":{"type":"integer"},"createDate":{"type":"date"}}}}

创建完再次查看

4、插入数据

POST indextest001/product
{undefined
  "title": "test title 001",
  "description": "es test 001 ",
  "price": 1.6,
  "onSale": "true",
  "type": 2,
  "createDate": "2021-01-08"
}

 然后查询一下所有数据，默认为match_all
 GET indextest001/product/
