3

安装部署Elastic Kibana

4

远程访问Kibana

5

开启Kibana-Console查看全部索引kibana：/_cat/indices?v

6

Kibana对比控制台命令

7

创建索引创建一个索引curl -X PUT "localhost:9200/student?pretty"kibana：PUT /student?prettyPUT /student

8

删除索引

9

添加文档

10

删除文档

11

更新文档-整体更新更新完整文档curl -X PUT "localhost:9200/student/class1/1?pretty" -H 'Content-Type: application/json' -d'{ "name": "zhangsan", "age": "22"}'kibanaPUT /student/class1/1{ "name": "zhangsan", "age": "22"}

12

更新文档-部分更新更新文档-部分更新curl -X POST "localhost:9200/student/class1/1/_update?pretty" -H 'Content-Type: application/json' -d'{ "doc" : { "name" : "yuanchunxu", "score": 100 }}'kibanaPOST /student/class1/1/_update{ "doc" : { "name" : "yuanchunxu", "score": 100 }}

13

查询文档查询一个文档请求：curl -X GET "localhost:9200/student/class1/1?pretty"kibana：GET /student/class1/1?pretty查询索引下全部文档curl -X GET "localhost:9200/student/class1/_search?pretty"kibana：GET /student/_searchGET /student/class1/_search

14

全局匹配查询全局搜索curl -X GET "localhost:9200/student/class1/_search?q=yellow"kibana:GET /student/_search?q=yellow

15

合并搜索（一）GET _mget{ "docs" : [ { "_index" : "student", "_type" : "class1", "_id" : 10 }, { "_index" : "student", "_type" : "class1", "_id" : 1, "_source": "age" } ]}curl -X GET "localhost:9200/_mget?pretty" -H 'Content-Type: application/json' -d'{ "docs" : [ { "_index" : "student", "_type" : "class1", "_id" : 10 }, { "_index" : "student", "_type" : "class1", "_id" : 1

16

合并搜索（二）GET _mget{ "docs" : [ { "_index" : "student", "_type" : "class1", "_id" : 10, "_source" : ["name", "age"] }, { "_index" : "student", "_type" : "class1", "_id" : 1, "_source": "age" } ]}

17

复合条件查询复合条件搜索+name:(yuan zhang) +age:>35 +(male)q=male <==> q=+(male)+ 前缀表示必须与查询条件匹配。- 前缀表示一定不与查询条件匹配。没有 + 或者 - 的所有其他条件都是可选的——匹配的越多，文档就越相关。

18

批量操作POST /_bulk{ "delete": { "_index": "student", "_type": "class1", "_id": "3" }} { "create": { "_index": "student", "_type": "class1", "_id": "101" }}{ "name": "xiaozhao" }{ "index": { "_index": "student", "_type": "class1" }}{ "name": "xiaoqiang", "age" : 15 }{ "update": { "_index": "student", "_type": "class1", "_id": "10"} }{ "doc" : {"age" : 32} } POST /student/class1/_bulk{ "delete": { "_id": "2" }} { "create": { "_id": "200" }}{ "name": "xiaozhang" }
