Additions and deletions change the use of the document API in Elasticsearch

What is the document? An object is equivalent to a record recording of MySQL

Reference:

Http://www.learnes.net/data/README.html

Curl 192.168.100.10:9200?preetycurl 192.168.100.10:9200/_count?pretty

Usage of curl in the shell

-x specifies that the request method defaults to-xget

-I also return the request result when I return the data

-D Data sent

This return value means that our index request has been successfully created, including _index, _type, and _id metadata, as well as a new element _version

_index nouns are equivalent to libraries in the database

_type equivalent to a table in a database

_ID is the ID (which can be specified and self-increment)

_index and _type and _id are the only ones that make up the data in the Elasticsearch store

Create a

Curl-xput 192.168.100.10:9200/website/blog/123-d ' {"title": "My First blog entry", "Text": "Just trying this out ...", "Date": "2016/01/01"} '

You can see the document that was created at the time you searched

[[email protected] ~]# Curl 192.168.100.10:9200/website/blog/123?pretty {"_index": "website", "_type": "blog", "_id" : "123", "_version": 1, "found": true, "_source": {"title": "My First blog entry", "Text": "Just trying th Is out ... "," date ":" 2014/01/01 "}}

For each situation found:

[Email protected] ~]# Curl 192.168.100.10:9200/website/blog/1235?pretty{"_index": "website", "_type": "blog", "_id" : "1235", "found": false}

_source is the content of the document. You can specify a value to return the field specified by the document

[Email protected] ~]# curl-i-xget "192.168.100.10:9200/logstash-2016.05.12/syslog/avsliby3bzztddjuagzh?_source= File,meesage&pretty "http/1.1 Okcontent-type:application/json;   charset=utf-8content-length:185{"_index": "logstash-2016.05.12", "_type": "Syslog", "_id": "Avsliby3bzztddjuagzh", "_version": 1, "found": true, "_source": {"file": "/var/log/messages"}}

Get multiple documents at once _mget

[[email protected] ~]# curl-i-xget 192.168.100.10:9200/logstash-2016.05.12/syslog/_mget?pretty-d ' {"IDs": ["2", "1"]} ' http/1.1 Okcontent-type:application/json; charset=utf-8content-length:230{"Docs": [{"_index": "logstash-2016.05.12", "_type": "Syslog", "_id": "2"  , "Found": false}, {"_index": "logstash-2016.05.12", "_type": "Syslog", "_id": "1", "found": false } ]}
