Elastic Stack的核心
Elasticsearch是一个分布式、RESTful风格的搜索和数据分析引擎，能够解决不断涌现出的各种用例。作为Elastic Stack的核心，它集中存储您的数据，帮助您发现意料之中以及意料之外的情况
The Elastic Stack，包括 Elasticsearch、Kibana、Beats和 Logstash(也称为ELK Stack)。能够安全可靠地获取任何来源、在何格式的数据，然后实时地对数据进行搜索、分析和可视化。Elaticsearch,简称为ES，ES是一个开源的高扩展的分布式全文搜索引擎,是整个ElasticStack 技术栈的核心。它可以近乎实时的存储、检索数据;本身扩展性很好，可以扩展到上百台服务器，处理PB级别的数据。

010-入门-HTTP-文档-创建（Put & Post）
索引已经创建好了，接下来我们来创建文档，并添加数据。这里的文档可以类比为关系型数据库中的表数据，添加的数据格式为JSON格式 在Postman中，向ES服务器发POST请求: http://127.0.0.1:9200/shopping/l_doc
POST http://10.221.154.185:9003/shopping/_doc
HTTP/1.1 400 Bad Request
content-type: application/json; charset=UTF-8
{
"error": {

"reason": "request body is required"
},
"status": 400
}
Response code: 400 (Bad Request); Time: 119ms; Content length: 163 bytes
POST请求体必须要有
POST http://10.221.154.185:9003/shopping/_doc
Accept: application/json
Content-Type: application/json
{
"name": "nancy",
"sex": "女",

这里能用PUT
PUT http://10.221.154.185:9003/shopping/_doc
HTTP/1.1 405 Method Not Allowed
Allow: POST

post中的返回体的 _id 是由ES软件生成的,
post同样的请求,返回的id结果不一样,说明我们的post请求不是幂等的
但是这个id 他很随机,不好记,我门也可以自己定义ID
幂等性的操作 POST
POST http://10.221.154.185:9003/shopping/_doc/1001
HTTP/1.1 201 Created

}
Response code: 201 (Created); Time: 123ms; Content length: 159 bytes
换PUT也可以了这回(幂等性)
