elasticsearch(三)：7.x 版本 基础增删改查 index doc _update 入门的第二步
参考官网
1、简单的增删改查，默认分片，默认类型
[root@vcontroller ~]# curl -X PUT "localhost:9200/customer?pretty"
{
"acknowledged" : true,
"shards_acknowledged" : true,
"index" : "customer"
}
[root@vcontroller ~]# curl -X GET 'localhost:9200/_cat/indices?v'
health status index uuid pri rep docs.count docs.deleted store.size pri.store.size

[root@vcontroller ~]# curl -X PUT "localhost:9200/customer/doc/1?pretty" -d '{"name": "shunzi2016"}'
{
"error" : "Content-Type header [application/x-www-form-urlencoded] is not supported",
"status" : 406
}
[root@vcontroller ~]# curl -X PUT "localhost:9200/customer/doc/1?pretty" -H "Content-Type: application/json" -d '{"name": "shunzi2016"}'
{
"_index" : "customer",
"_type" : "doc",
"_id" : "1",
"_version" : 1,
"result" : "created",
"_shards" : {
"total" : 2,
"successful" : 1,
"failed" : 0
},
"_seq_no" : 0,
"_primary_term" : 1
}
[root@vcontroller ~]# curl -X GET "localhost:9200/customer/doc/1?pretty"
{
"_index" : "customer",
"_type" : "doc",
"_id" : "1",
"_version" : 1,
"_seq_no" : 0,
"_primary_term" : 1,
"found" : true,
"_source" : {
"name" : "shunzi2016"
}
}
[root@vcontroller ~]# curl -X DELETE "localhost:9200/customer/doc/1?pretty"
{
"_index" : "customer",
"_type" : "doc",
"_id" : "1",
"_version" : 2,
"result" : "deleted",
"_shards" : {
"total" : 2,
"successful" : 1,
"failed" : 0
},
"_seq_no" : 1,
"_primary_term" : 1
}
[root@vcontroller ~]# curl -X GET "localhost:9200/customer/doc/1?pretty"
{
"_index" : "customer",
"_type" : "doc",
"_id" : "1",
"found" : false
}
[root@vcontroller ~]# curl -X PUT "localhost:9200/customer/doc/1?pretty" -H "Content-Type:application/json" -d '{"name": "shunzi2016"}'
{
"_index" : "customer",
"_type" : "doc",
"_id" : "1",
"_version" : 1,
"result" : "created",
"_shards" : {
"total" : 2,
"successful" : 1,
"failed" : 0
},
"_seq_no" : 2,
"_primary_term" : 1
}
[root@vcontroller ~]# curl -X POST "localhost:9200/customer/doc/1/_update?pretty" -H "Content-Type:application/json" -d '{"doc": {"name":"shunzi2016", "age": 30}}'
{
"_index" : "customer",
"_type" : "doc",
"_id" : "1",
"_version" : 2,
"result" : "updated",
"_shards" : {
"total" : 2,
"successful" : 1,
"failed" : 0
},
"_seq_no" : 3,
"_primary_term" : 1
}
[root@vcontroller ~]# curl -X GET "localhost:9200/customer/doc?pretty"
{
"error" : "Incorrect HTTP method for uri [/customer/doc?pretty] and method [GET], allowed: [POST]",
"status" : 405
}
[root@vcontroller ~]# curl -X GET "localhost:9200/customer/doc/1?pretty"
{
"_index" : "customer",
"_type" : "doc",
"_id" : "1",
"_version" : 2,
"_seq_no" : 3,
"_primary_term" : 1,
"found" : true,
"_source" : {
"name" : "shunzi2016",
"age" : 30
}
}
[root@vcontroller ~]# curl -X GET "localhost:9200/customer"
{"customer":{"aliases":{},"mappings":{"properties":{"age":{"type":"long"},"name":{"type":"text","fields":{"keyword":{"type":"keyword","ignore_above":256}}}}},"settings":{"index":{"routing":{"allocation":{"include":{"_tier_preference":"data_content"}}},"number_of_shards":"1","provided_name":"customer","creation_date":"1611825831984","number_of_replicas":"1","uuid":"Mb-4XQCzRDyf2Ins9oAJIg","version":{"created":"7100299"}}}}}[root@vcontroller ~]# curl -X GET "localhost:9200/customer/doc"

[root@vcontroller ~]#
# 部分更新
[root@vcontroller ~]# curl -X POST "localhost:9200/customer/doc/1/_update?pretty" -H "Content-Type:application/json" -d '{"doc": {"name":"shunzi20162222", "age": 30}}'
{
"_index" : "customer",
"_type" : "doc",
"_id" : "1",
"_version" : 3,
"result" : "updated",
"_shards" : {
"total" : 2,
"successful" : 1,
"failed" : 0
},
"_seq_no" : 4,
"_primary_term" : 1
}
[root@vcontroller ~]# curl -X GET "localhost:9200/customer/doc/1?pretty"
{
"_index" : "customer",
"_type" : "doc",
"_id" : "1",
"_version" : 3,
"_seq_no" : 4,
"_primary_term" : 1,
"found" : true,
"_source" : {
"name" : "shunzi20162222",
"age" : 30
}
}1.1 可以越过单独创建索引的过程，直接创建索引以及插入数据
[root@vcontroller ~]# curl -X PUT -H "Content-Type:application/json" "localhost:9200/person/info/01" -d '{"id":"23456","name":"张三"}'
{"_index":"person","_type":"info","_id":"01","_version":1,"result":"created","_shards":{"total":2,"successful":1,"failed":0},"_seq_no":0,"_primary_term":1}
1.2 在DSL语句结尾加上？pretty 可以更清晰直观的看到执行结果，否则当数据量大时，会眼花缭乱
[root@vcontroller ~]# curl -X PUT -H "Content-Type:application/json" "localhost:9200/person/info/03?pretty" -d '{"id":"23ssssssw","name":"王八"}'
{
"_index" : "person",
"_type" : "info",
"_id" : "03",
"_version" : 1,
"result" : "created",
"_shards" : {
"total" : 2,
"successful" : 1,
"failed" : 0
},
"_seq_no" : 3,
"_primary_term" : 1
}1.3 针对同 id，不同内容 的数据，put 两次会直接进行覆盖
_update 是部分更新，
[root@vcontroller ~]# curl -X PUT -H "Content-Type:application/json" "localhost:9200/person/info/04?pretty" -d '{"id":"5","name":"QQ"}'
{
"_index" : "person",
"_type" : "info",
"_id" : "04",
"_version" : 1,
"result" : "created",
"_shards" : {
"total" : 2,
"successful" : 1,
"failed" : 0
},
"_seq_no" : 4,
"_primary_term" : 1
}
[root@vcontroller ~]# curl -X GET localhost:9200/person/info/04?pretty
{
"_index" : "person",
"_type" : "info",
"_id" : "04",
"_version" : 1,
"_seq_no" : 4,
"_primary_term" : 1,
"found" : true,
"_source" : {
"id" : "5",
"name" : "QQ"
}
}
[root@vcontroller ~]# curl -X PUT -H "Content-Type:application/json" "localhost:9200/person/info/04?pretty" -d '{"id":"5","name":"微信"}'
{
"_index" : "person",
"_type" : "info",
"_id" : "04",
"_version" : 2,
"result" : "updated",
"_shards" : {
"total" : 2,
"successful" : 1,
"failed" : 0
},
"_seq_no" : 5,
"_primary_term" : 1
}
[root@vcontroller ~]# curl -X GET localhost:9200/person/info/04?pretty
{
"_index" : "person",
"_type" : "info",
"_id" : "04",
"_version" : 2,
"_seq_no" : 5,
"_primary_term" : 1,
"found" : true,
"_source" : {
"id" : "5",
"name" : "微信"
}
}
1.4 查看
2、条件查询
2.1 按照 索引，类型， id 查询
[root@vcontroller ~]# curl -X GET localhost:9200/ykc/active/01?pretty
{
"_index" : "ykc",
"_type" : "active",
"_id" : "01",
"_version" : 1,
"_seq_no" : 0,
"_primary_term" : 1,
"found" : true,
"_source" : {
"id" : "121213",
"name" : "李四"
}
}2.2 无条件查询全部数据
[root@vcontroller ~]# curl -X GET localhost:9200/_search?pretty
{
"took" : 111,
"timed_out" : false,
"_shards" : {
"total" : 3,
"successful" : 3,
"skipped" : 0,
"failed" : 0
},
"hits" : {
"total" : {
"value" : 2,
"relation" : "eq"
},
"max_score" : 1.0,
"hits" : [
{
"_index" : "customer",
"_type" : "doc",
"_id" : "1",
"_score" : 1.0,
"_source" : {
"name" : "韩小顺2222",
"age" : 30
}
},
{
"_index" : "person",
"_type" : "info",
"_id" : "01",
"_score" : 1.0,
"_source" : {
"id" : "121213",
"name" : "李四"
}
}
]
}
}2.3 模糊查询
[root@vcontroller ~]# curl -H 'Content-Type: application/json' localhost:9200/person/info/_search?pretty -d '{"query":{"match":{"name":"李"}}}'
{
"took" : 44,
"timed_out" : false,
"_shards" : {
"total" : 1,
"successful" : 1,
"skipped" : 0,
"failed" : 0
},
"hits" : {
"total" : {
"value" : 1,
"relation" : "eq"
},
"max_score" : 0.2876821,
"hits" : [
{
"_index" : "person",
"_type" : "info",
"_id" : "01",
"_score" : 0.2876821,
"_source" : {
"id" : "121213",
"name" : "李四"
}
}
]
}
}2.4 模糊查询，返回指定的字段列数据
[root@vcontroller ~]# curl -H 'Content-Type: application/json' 'localhost:9200/person/info/_search?_source=name&pretty=true' -d '{"query":{"match":{"name":"李"}}}'
{
"took" : 3,
"timed_out" : false,
"_shards" : {
"total" : 1,
"successful" : 1,
"skipped" : 0,
"failed" : 0
},
"hits" : {
"total" : {
"value" : 1,
"relation" : "eq"
},
"max_score" : 0.2876821,
"hits" : [
{
"_index" : "person",
"_type" : "info",
"_id" : "01",
"_score" : 0.2876821,
"_source" : {
"name" : "李四"
}
}
]
}
}2.5 引号的使用错误： 双重 双引号
[root@vcontroller ~]# curl -X PUT -H "Content-Type:application/json" "localhost:9200/person/info/01" -d "{"id":"23456","name":"张三"}"
{"error":{"root_cause":[{"type":"mapper_parsing_exception","reason":"failed to parse"}],"type":"mapper_parsing_exception","reason":"failed to parse","caused_by":{"type":"json_parse_exception","reason":"Unexpected character ('i' (code 105)): was expecting double-quote to start field name\n at [Source: (byte[])\"{id:23456,name:张三}\"; line: 1, column: 3]"}},"status":400}2.6 查询当前类型所有数据：
