索引操作

//创建一个索引，pretty表示打印添加状态

curl -X PUT "localhost:9200/customer?pretty"

//获取索引列表
curl -X GET "localhost:9200/_cat/indices?v"

//向索引中添加一个文档，指定ID为1，如果索引不存在es会自动创建
curl -X PUT "localhost:9200/customer/_doc/1?pretty" -H 'Content-Type: application/json' -d'
{
  "name": "John Doe"
}'

//向索引中添加一个文档，没有指定ID，es将自动创建
curl -X POST "localhost:9200/customer/_doc?pretty" -H 'Content-Type: application/json' -d'
{
  "name": "Jane Doe"
}'

//检索编入索引的文档
curl -X GET "localhost:9200/customer/_doc/1?pretty"

//删除索引
curl -X DELETE "localhost:9200/customer?pretty"

更新文档

//更新ID为1的文档
curl -X POST "localhost:9200/customer/_doc/1/_update?pretty" -H 'Content-Type: application/json' -d'
{
  "doc": { "name": "Jane Doe" }
}'

//更新ID为1的文档，并且增加属性
curl -X POST "localhost:9200/customer/_doc/1/_update?pretty" -H 'Content-Type: application/json' -d'
{
  "doc": { "name": "Jane Doe", "age": 20 }
}'

//使用脚本更新文档，ctx._source代表当前要更新的文档（此处表示年龄在原来的基础上再加5）
curl -X POST "localhost:9200/customer/_doc/1/_update?pretty" -H 'Content-Type: application/json' -d'
{
  "script" : "ctx._source.age += 5"
}'

删除文档

//删除文档指定ID为2
curl -X DELETE "localhost:9200/customer/_doc/2?pretty"

批量处理：

//批量插入两条数据，ID分别为3和4
curl -X POST "localhost:9200/customer/_doc/_bulk?pretty" -H 'Content-Type: application/json' -d'
{"index":{"_id":"3"}}
{"name": "John Doe" }
{"index":{"_id":"4"}}
{"name": "Jane Doe" }
'

//此示例更新第一个文档（ID为1），然后在一个批量操作中删除第二个文档（ID为2）：
curl -X POST "localhost:9200/customer/_doc/_bulk?pretty" -H 'Content-Type: application/json' -d'
{"update":{"_id":"1"}}
{"doc": { "name": "John Doe becomes Jane Doe" } }
{"delete":{"_id":"2"}}
