Elasticsearch利用Kibana操作

Elasticsearch汇总

Kibana的安装与使用，安装略

1.在Kibana的Dev Tools中进行操作

(1）快速检查集群的健康状况:	     GET /_cat/health?v
(2）快速查看集群中有哪些索引:    GET /_cat/indices?v
(3）简单的索引操作
	 	创建索引：PUT /test_index?pretty
	 	删除索引：DELETE /test_index?pretty

（4）商品的CRUD操作：

 4.1 新增商品：新增文档，建立索引  PUT /index/type/id 
	     		（index表示 数据库名，type表示 数据库表名，id表示  主键id）


例子：
PUT /ecommerce/product/1
{
    "name" : "gaolujie yagao",
    "desc" :  "gaoxiao meibai",
    "price" :  30,
    "producer" :      "gaolujie producer",
    "tags": [ "meibai", "fangzhu" ]
}


结果：
{
  "_index": "ecommerce",
  "_type": "product",
  "_id": "1",
  "_version": 1,
  "result": "created",
  "_shards": {
    "total": 2,
    "successful": 1,
    "failed": 0
  },
  "created": true
}


例子：
PUT /ecommerce/product/2
{
    "name" : "jiajieshi yagao",
    "desc" :  "youxiao fangzhu",
    "price" :  25,
    "producer" :      "jiajieshi producer",
    "tags": [ "fangzhu" ]
}

PUT /ecommerce/product/3
{
    "name" : "zhonghua yagao",
    "desc" :  "caoben zhiwu",
    "price" :  40,
    "producer" :      "zhonghua producer",
    "tags": [ "qingxin" ]
}

es会自动建立index和type，不需要提前创建，而且es默认会对document每个field都建立倒排索引，让其可以被搜索

4.2 查询商品 ：检索文档

GET /index/type/id （根据id，也就是主键到 index数据库中，type表中去查询结果）

例子：
GET /ecommerce/product/1

结果：
{
  "_index": "ecommerce",
  "_type": "product",
  "_id": "1",
  "_version": 1,
  "found": true,
  "_source": {
    "name": "gaolujie yagao",
    "desc": "gaoxiao meibai",
    "price": 30,
    "producer": "gaolujie producer",
    "tags": [
      "meibai",
      "fangzhu"
    ]
  }
}

4.3 修改商品：替换文档

例子：
PUT /ecommerce/product/1
{
    "name" : "jiaqiangban gaolujie yagao",
    "desc" :  "gaoxiao meibai",
    "price" :  30,
    "producer" :      "gaolujie producer",
    "tags": [ "meibai", "fangzhu" ]
}

结果：
{
  "_index": "ecommerce",
  "_type": "product",
  "_id": "1",
  "_version": 2,
  "result": "updated",
  "_shards": {
    "total": 2,
    "successful": 1,
    "failed": 0
  },
  "created": false
}

例子：
 PUT /ecommerce/product/1
{
    "name" : "jiaqiangban gaolujie yagao"
}

替换方式有一个不好，即使必须带上所有的field，才能去进行信息的修改

4.4 修改商品：更新文档

例子：
POST /ecommerce/product/1/_update
{
  "doc": {
    "name": "jiaqiangban gaolujie yagao"
  }
}

结果：
{
  "_index": "ecommerce",
  "_type": "product",
  "_id": "1",
  "_version": 8,
  "result": "updated",
  "_shards": {
    "total": 2,
    "successful": 1,
    "failed": 0
  }
}

4.5 删除商品：删除文档
例子：
DELETE /ecommerce/product/1

结果：
{
  "found": true,
  "_index": "ecommerce",
  "_type": "product",
  "_id": "1",
  "_version": 9,
  "result": "deleted",
  "_shards": {
    "total": 2,
    "successful": 1,
    "failed": 0
  }
}
