ES文档操作
Elasticsearch之-文档操作
一 新增文档
#新增一个id为1的书籍(POST和PUT都可以)
POST lqz/_doc/1/_create
#POST lqz/_doc/1
#POST lqz/_doc 会自动创建id,必须用Post
{
"title":"红楼梦",
"price":12,
"publish_addr":{
"province":"黑龙江",
"city":"鹤岗"
},
"publish_date":"2013-11-11",
"read_num":199,
"tag":["古典","名著"]
}
二 查询文档
#查询lqz索引下id为7的文档
GET lqz/_doc/7
#查询lqz索引下id为7的文档,只要title字段
GET lqz/_doc/7?_source=title
#查询lqz索引下id为7的文档,只要title和price字段
GET lqz/_doc/7?_source=title,price
#查询lqz索引下id为7的文档,要全部字段
GET lqz/_doc/7?_source
三 修改文档
#修改文档(覆盖修改)
PUT lqz/_doc/10
{
"title":"xxxx",
"price":333,
"publish_addr":{
"province":"黑龙江",
"city":"福州"
}
}
#修改文档,增量修改,只修改某个字段(注意是post)
POST lqz/_update/10
{
"doc":{
"title":"修改"
}
}
四 删除文档
#删除文档id为10的
DELETE lqz/_doc/10
五 批量操作之_mget
#批量获取lqz索引_doc类型下id为2的数据和lqz2索引_doc类型下id为1的数据
GET _mget
{
"docs":[
{
"_index":"lqz",
"_type":"_doc",
"_id":2
},
{
"_index":"lqz2",
"_type":"_doc",
"_id":1
}
]
}
#批量获取lqz索引下id为1和2的数据
GET lqz/_mget
{
"docs":[
{
"_id":2
},
{
"_id":1
}
]
}
#同上
GET lqz/_mget
{
"ids":[1,2]
}
六 批量操作之 bulk
PUT test/_doc/2/_create
{
"field1" : "value22"
}
POST _bulk
{ "index" : { "_index" : "test", "_id" : "1" } }
{ "field1" : "value1" }
{ "delete" : { "_index" : "test", "_id" : "2" } }
{ "create" : { "_index" : "test", "_id" : "3" } }
{ "field1" : "value3" }
{ "update" : {"_id" : "1", "_index" : "test"} }
{ "doc" : {"field2" : "value2"} }
