官方文档：https://www.elastic.co/guide/en/elasticsearch/reference/current/index.html

批量插入数据的文档：https://www.elastic.co/guide/en/elasticsearch/reference/7.5/docs-bulk.html

增，删，改，查 全部遵循refult 风格

使用postman来新建一个文档

1 增加

http://localhost:9200/blog1/article/1

{        "id":1,        "title":"在弹性搜索中创建索引时，"        ,"content":"为什么呢？因为mappings里有写参数在elasticsearch6版本里不支持了，index_analyzer就不支持了，改成了analyzer，改过来，就好了，可以建立索引成功"}

2 查询

根据id来查询 GET : http://localhost:9200/blog1/article/1

根据关键字查询 POST：http://localhost:9200/blog1/article/_search

{        "query":{                "term":{                        "content":"因"                }        }}

使用字符串查询(对查询条件进行分词之后再进行查询) POST : http://localhost:9200/blog1/article/_search

{        "query":{                "query_string":{                        "default_field":"content",                        "query":"创建索引"                }        }}

# 自带的分词器POST _analyze{  "analyzer": "standard",  "text": "The 2 QUICK Brown-Foxex jumped over the lazy dog's bone."}POST _analyze{  "analyzer": "simple",  "text": "The 2 QUICK Brown-Foxex jumped over the lazy dog's bone."}POST _analyze{  "analyzer": "whitespace",  "text": "The 2 QUICK Brown-Foxex jumped over the lazy dog's bone."}POST _analyze{  "analyzer": "stop",  "text": "The 2 QUICK Brown-Foxex jumped over the lazy dog's bone."}POST _analyze{  "analyzer": "keyword",  "text": "The 2 QUICK Brown-Foxex jumped over the lazy dog's bone."}POST _analyze{  "analyzer": "pattern",  "text": "The 2 QUICK Brown-Foxex jumped over the lazy dog's bone."}

#创建mapping的简介步骤#1 向es中插入一条数据 （es7中要使用_doc）PUT my_index_test/_doc/1{  "referrer":"-",  "response_code":"200",  "remote_ip":"192.168.1.1",  "method":"post",  "user_name":"zhangsan",  "http_version":"1.1",  "body_sent":{    "bytes":"0"  },  "url":"/query/list"}#2 获取刚刚创建的index  mappingGET my_index_test/_mapping#3 删除该indexDELETE my_index_test#4 改造刚刚获取的index mappingPUT my_index_test{  "mappings": {    "properties": {      "body_sent": {        "properties": {          "bytes": {            "type": "text"          }        }      },      "http_version": {        "type": "keyword"      },      "method": {        "type": "keyword"      },      "referrer": {        "type": "keyword"      },      "remote_ip": {        "type": "ip"      },      "response_code": {        "type": "keyword"      },      "url": {        "type": "text"      },      "user_name": {        "type": "text"      }    }  }}#5 校验刚才插入的数据GET my_index_test/_doc/1
