1.新增
使用put进行新增，必须使用id。
PUT /nba/_doc/1
{
"name":"哈登",
"team_name":"⽕箭",
"position":"得分后卫",
"play_year":"10",
"jerse_no":"13"
}
结果：
{
"_index" : "nba",
"_type" : "_doc",
"_id" : "1",
"_version" : 1,
"result" : "created",
"_shards" : {
"total" : 2,
"successful" : 1,
"failed" : 0
},
"_seq_no" : 0,
"_primary_term" : 3
}
2.新增
这种不指定id
POST /nba/_doc/
{
"name":"哈登",
"team_name":"⽕箭",
"position":"得分后卫",
"play_year":"10",
"jerse_no":"13"
}
结果：
{
"_index" : "nba",
"_type" : "_doc",
"_id" : "xpGZJnEB_xXvz4I-POcw",
"_version" : 1,
"result" : "created",
"_shards" : {
"total" : 2,
"successful" : 1,
"failed" : 0
},
"_seq_no" : 1,
"_primary_term" : 3
}
3.查找
GET /nba/_doc/1
4.说明
不存在的索引，新增文档，也可以新建出索引。不过，实验发现都是keyword类型。
PUT /wba/_doc/1
{
"name":"哈登2",
"team_name":"⽕箭",
"position":"得分后卫",
"play_year":"10",
"jerse_no":"13"
}
结果：
{
"_index" : "wba",
"_type" : "_doc",
"_id" : "1",
"_version" : 1,
"result" : "created",
"_shards" : {
"total" : 2,
"successful" : 1,
"failed" : 0
},
"_seq_no" : 0,
"_primary_term" : 1
}
查看索引：
GET /wba
结果：
{
"wba" : {
"aliases" : { },
"mappings" : {
"properties" : {
"jerse_no" : {
"type" : "text",
"fields" : {
"keyword" : {
"type" : "keyword",
"ignore_above" : 256
}
}
},
"name" : {
"type" : "text",
"fields" : {
"keyword" : {
"type" : "keyword",
"ignore_above" : 256
}
}
},
"play_year" : {
"type" : "text",
"fields" : {
"keyword" : {
"type" : "keyword",
"ignore_above" : 256
}
}
},
"position" : {
"type" : "text",
"fields" : {
"keyword" : {
"type" : "keyword",
"ignore_above" : 256
}
}
},
"team_name" : {
"type" : "text",
"fields" : {
"keyword" : {
"type" : "keyword",
"ignore_above" : 256
}
}
}
}
},
"settings" : {
"index" : {
"creation_date" : "1585491459227",
"number_of_shards" : "1",
"number_of_replicas" : "1",
"uuid" : "5919dIHxQYGZXQ4DrtuCyQ",
"version" : {
"created" : "7020099"
},
"provided_name" : "wba"
}
}
}
}
5.指定操作类型
为啥需要呢
PUT /nba/_doc/1
{
"name":"哈登2",
"team_name":"⽕箭",
"position":"得分后卫",
"play_year":"10",
"jerse_no":"13"
}
GET /nba/_doc/1
结果：
{
"_index" : "nba",
"_type" : "_doc",
"_id" : "1",
"_version" : 5,
"_seq_no" : 5,
"_primary_term" : 3,
"found" : true,
"_source" : {
"name" : "哈登2",
"team_name" : "⽕箭",
"position" : "得分后卫",
"play_year" : "10",
"jerse_no" : "13"
}
}
然后，想新增
PUT /nba/_doc/1
{
"name":"哈登",
"team_name":"⽕箭",
"position":"得分后卫",
"play_year":"10",
"jerse_no":"13"
}
GET /nba/_doc/1
结果：
# PUT /nba/_doc/1
{
"_index" : "nba",
"_type" : "_doc",
"_id" : "1",
"_version" : 6,
"result" : "updated",
"_shards" : {
"total" : 2,
"successful" : 1,
"failed" : 0
},
"_seq_no" : 6,
"_primary_term" : 3
}
# GET /nba/_doc/1
{
"_index" : "nba",
"_type" : "_doc",
"_id" : "1",
"_version" : 6,
"_seq_no" : 6,
"_primary_term" : 3,
"found" : true,
"_source" : {
"name" : "哈登",
"team_name" : "⽕箭",
"position" : "得分后卫",
"play_year" : "10",
"jerse_no" : "13"
}
}
发现，不小心把前面的给覆盖了。
然后，怎么解决呢？
PUT /nba/_doc/1?op_type=create
{
"name":"哈登2",
"team_name":"⽕箭",
"position":"得分后卫",
"play_year":"10",
"jerse_no":"13"
}
结果：
{
"error": {
"root_cause": [
{
"type": "version_conflict_engine_exception",
"reason": "[1]: version conflict, document already exists (current version [6])",
"index_uuid": "q_fuLgv1Sjyb8yncRsCWZQ",
"shard": "0",
"index": "nba"
}
],
"type": "version_conflict_engine_exception",
"reason": "[1]: version conflict, document already exists (current version [6])",
"index_uuid": "q_fuLgv1Sjyb8yncRsCWZQ",
"shard": "0",
"index": "nba"
},
"status": 409
}
6.批量查询
post方式,get也可以
POST /_mget
{
"docs":[
{
"_index": "nba",
"_type": "_doc",
"_id": 2
},
{
"_index": "songs",
"_type": "_doc",
"_id": 1
}
]
}
效果：
#! Deprecation: [types removal] Specifying types in multi get requests is deprecated.
{
"docs" : [
{
"_index" : "nba",
"_type" : "_doc",
"_id" : "2",
"_version" : 1,
"_seq_no" : 7,
"_primary_term" : 3,
"found" : true,
"_source" : {
"name" : "哈登2",
"team_name" : "⽕箭",
"position" : "得分后卫",
"play_year" : "10",
"jerse_no" : "13"
}
},
{
"_index" : "songs",
"_type" : "_doc",
"_id" : "1",
"_version" : 8,
"_seq_no" : 7,
"_primary_term" : 1,
"found" : true,
"_source" : {
"name" : "说好不哭",
"author" : "周杰伦"
}
}
]
}
7.更加简化的查询方式
POST /nba/_doc/_mget
{
"docs":[
{
"_id":"1"
},
{
"_id":"2"
}
]
}
结果：
#! Deprecation: [types removal] Specifying types in multi get requests is deprecated.
{
"docs" : [
{
"_index" : "nba",
"_type" : "_doc",
"_id" : "1",
"_version" : 6,
"_seq_no" : 6,
"_primary_term" : 3,
"found" : true,
"_source" : {
"name" : "哈登",
"team_name" : "⽕箭",
"position" : "得分后卫",
"play_year" : "10",
"jerse_no" : "13"
}
},
{
"_index" : "nba",
"_type" : "_doc",
"_id" : "2",
"_version" : 1,
"_seq_no" : 7,
"_primary_term" : 3,
"found" : true,
"_source" : {
"name" : "哈登2",
"team_name" : "⽕箭",
"position" : "得分后卫",
"play_year" : "10",
"jerse_no" : "13"
}
}
]
}
8.更加简化的mget
POST /nba/_doc/_mget
{
"ids":["1","2"]
}
9.修改
只更新了一部分字段
POST /nba/_update/2
{
"doc":{
"play_year":"1000",
"jerse_no":"1300"
}
}
GET /nba/_doc/2
结果：
# POST /nba/_update/2
{
"_index" : "nba",
"_type" : "_doc",
"_id" : "2",
"_version" : 8,
"result" : "updated",
"_shards" : {
"total" : 2,
"successful" : 1,
"failed" : 0
},
"_seq_no" : 14,
"_primary_term" : 3
}
# GET /nba/_doc/2
{
"_index" : "nba",
"_type" : "_doc",
"_id" : "2",
"_version" : 8,
"_seq_no" : 14,
"_primary_term" : 3,
"found" : true,
"_source" : {
"name" : "哈登2",
"team_name" : "⽕箭",
"position" : "得分后卫",
"play_year" : "1000",
"jerse_no" : "1300"
}
}
10.新增一个字段
POST /nba/_update/2
{
"script":"ctx._source.age=19"
}
GET /nba/_doc/2
结果：
# POST /nba/_update/2
{
"_index" : "nba",
"_type" : "_doc",
"_id" : "2",
"_version" : 9,
"result" : "updated",
"_shards" : {
"total" : 2,
"successful" : 1,
"failed" : 0
},
"_seq_no" : 15,
"_primary_term" : 3
}
# GET /nba/_doc/2
{
"_index" : "nba",
"_type" : "_doc",
"_id" : "2",
"_version" : 9,
"_seq_no" : 15,
"_primary_term" : 3,
"found" : true,
"_source" : {
"name" : "哈登2",
"team_name" : "⽕箭",
"position" : "得分后卫",
"play_year" : "1000",
"jerse_no" : "1300",
"age" : 19
}
}
11.删除一个文档
POST /nba/_update/2
{
"script":"ctx._source.remove(\"age\")"
}
GET /nba/_doc/2
结果：
# POST /nba/_update/2
{
"_index" : "nba",
"_type" : "_doc",
"_id" : "2",
"_version" : 10,
"result" : "updated",
"_shards" : {
"total" : 2,
"successful" : 1,
"failed" : 0
},
"_seq_no" : 17,
"_primary_term" : 3
}
# GET /nba/_doc/2
{
"_index" : "nba",
"_type" : "_doc",
"_id" : "2",
"_version" : 10,
"_seq_no" : 17,
"_primary_term" : 3,
"found" : true,
"_source" : {
"name" : "哈登2",
"team_name" : "⽕箭",
"position" : "得分后卫",
"play_year" : "1000",
"jerse_no" : "1300"
}
}
12.根据指定参数，更新文档
POST /nba/_update/3
{
"script": {
"source": "ctx._source.allstar += params.allstar",
"params": {
"allstar": 4
}
},
"upsert": {
"allstar": 1
}
}
结果：
# POST /nba/_update/3
{
"_index" : "nba",
"_type" : "_doc",
"_id" : "3",
"_version" : 3,
"result" : "updated",
"_shards" : {
"total" : 2,
"successful" : 1,
"failed" : 0
},
"_seq_no" : 20,
"_primary_term" : 3
}
# GET /nba/_doc/3
{
"_index" : "nba",
"_type" : "_doc",
"_id" : "3",
"_version" : 3,
"_seq_no" : 20,
"_primary_term" : 3,
"found" : true,
"_source" : {
"allstar" : 9
}
}
发现这里version是3。
第一次不存在则为1，第二次是5，第三次是9.
upsert：不存在，就是后面的数，存在就使用上面的数据
13.删除
DELETE /nba/_doc/3 GET /nba/_doc/3
结果：
# DELETE /nba/_doc/3
{
"_index" : "nba",
"_type" : "_doc",
"_id" : "3",
"_version" : 4,
"result" : "deleted",
"_shards" : {
"total" : 2,
"successful" : 1,
"failed" : 0
},
"_seq_no" : 21,
"_primary_term" : 3
}
# GET /nba/_doc/3
{
"_index" : "nba",
"_type" : "_doc",
"_id" : "3",
"found" : false
}
