To create an index library:
Curl-xpost HTTP://LOCALHOST:9200/BJSXT
The index library name must be all lowercase, cannot begin with an underscore, and cannot contain commas

To create an index:
Curl-xpost HTTP://LOCALHOST:9200/BJSXT/EMPLOYEE/1-D
‘{
"First_Name": "John",
"Last_Name": "Smith",
"Age": 25,
"About": "I love to go rock climbing",
"Interests": ["Sports", "music"]
}‘

If you want to make sure that we are creating new content, use the op_type=create, _create
Curl-xput http://localhost:9200/bjsxt/emp/2?op_type=create-d ' {"name": "Zs", "Age": 25} '
Curl-xput http://localhost:9200/bjsxt/emp/2/_create-d ' {"name": "Laoxiao", "Age": 25} '
Back to 201 created/409 Conflict

Query based on employee ID:
Curl-xget Http://localhost:9200/bjsxt/employee/1?pretty
After curl add the-i parameter, you can get the feedback header file
Curl-i ' Http://localhost:9200/bjsxt/employee/1?pretty '
Add the pretty parameter to any query string, ES can get JSON results that are easy to recognize

Get Query Index
Retrieves a portion of a document, showing only the Name,age field
Curl-xget Http://localhost:9200/bjsxt/employee/1?_source=name,age
If you only need data from source
Curl-xget Http://localhost:9200/bjsxt/employee/1/_source
Query all
Curl-xget Http://localhost:9200/bjsxt/employee/_search
Query based on criteria
Curl-xget Http://localhost:9200/bjsxt/employee/_search?q=last_name:Smith

Get multiple documents using the Mget API
Curl-xget http://localhost:9200/_mget?pretty-d ' {
"Docs": [{
"_index": "BJSXT",
"_type": "EMP",
"_id": 2,
"_source": "Name"
},{
"_index": "Website",
"_type": "Blog",
"_ID": 2
}]}‘

If you only want to check if the document exists, you can use head instead of the Get method, which will return only the HTTP header file:
Curl-i-xhead HTTP://LOCALHOST:9200/BJSXT/EMPLOYEE/1

Version control for Elasticsearch
First get the document that needs to be modified, get the version (_version) number
Curl-xget HTTP://LOCALHOST:9200/BJSXT/EMPLOYEE/1
The version number is passed when the update operation is performed
Curl-xput http://localhost:9200/bjsxt/employee/1?version=2-d ' {"name": "Zs", "Age": 25} '
