Elasticearch(用POSTMAN测试)

创建索引库

PUT/POST方式提交
http://localhost:9200/my_course

地址： http://localhost:9200/my_course

带上下方JSON数据

举例：用POSTMAN提交找到Body中的raw并以JSON数据提交

{
	"settings": {
		"index": {
			"number_of_shards": 1,
			"number_of_replicas": 0
		}
	}
}

提交成功后应返回以下JSON数据

{
    "acknowledged": true,
    "shards_acknowledged": true,
    "index": "my_course"
}

设置映射

POST提交
http://localhost:9200/my_course/doc/_mapping

地址： http://localhost:9200/my_course/doc/_mapping

带上下方JSON数据

举例：用POSTMAN提交找到Body中的raw并以JSON数据提交

{
	"properties": {
		"description": {
			"type": "text",
			"analyzer": "ik_max_word", //是否用ik
			"search_analyzer": "ik_smart"
		},
		"name": {
			"type": "text",
			"analyzer": "ik_max_word",
			"search_analyzer": "ik_smart"
		},
		"pic": {
			"type": "text",
			"index": false
		},
		"price": {
			"type": "float"
		},
		"studymodel": {
			"type": "keyword"
		},
		"timestamp": {
			"type": "date",
			"format": "yyyy-MM-dd HH:mm:ss||yyyy-MM-dd"
		}
	}
}

提交成功后应返回以下数据

{
    "acknowledged": true
}

把数据写入索引库

POST提交
http://localhost:9200/my_course/doc/3

 http://localhost:9200/my_course/doc/3    注：后面跟的3是数据的id

带上下方JSON数据

举例：用POSTMAN提交找到Body中的raw并以JSON数据提交

{
"name": "java编程基础", 
"description": "java语言是世界第一编程语言，在软件开发领域使用人数最多。", 
"pic":"group1/M00/00/01/wKhlQFqO4MmAOP53AAAcwDwm6SU490.jpg", 
"studymodel": "201001" ,
"timestamp":"2020-01-28 18:28:58" 
} 

提交成功后应返回以下数据

{
    "_index": "my_course",
    "_type": "doc",
    "_id": "3",  //这里的id就是上面地址跟的参数id
    "_version": 1,
    "result": "created",
    "_shards": {
        "total": 1,    
        "successful": 1, //成功
        "failed": 0
    },
    "_seq_no": 2,
    "_primary_term": 1
}

查询

GET提交
http://localhost:9200/my_course/doc/_search?q=name:java

 http://localhost:9200/my_course/doc/_search?q=name:java
   注：q=是固定语法，而name是根据name去查，如果改成description就意思是根据description去查询
   ：后面跟的是查询内容	

查询成功应返回以下数据

{
    "took": 4,
    "timed_out": false,
    "_shards": {
        "total": 1,
        "successful": 1,
        "skipped": 0,
        "failed": 0
    },
    "hits": {
        "total": 1,

        "hits": [
            {
                "_index": "my_course",
                "_type": "doc",
                "_id": "3",
                "_score": 0.9331132,
                "_source": {
                    "name": "java编程基础",
                    "description": "java语言是世界第一编程语言，在软件开发领域使用人数最多。",
                    "pic": "group1/M00/00/01/wKhlQFqO4MmAOP53AAAcwDwm6SU490.jpg",
                    "studymodel": "201001",
                    "timestamp": "2020-01-28 18:28:58"
                }
            }
        ]
    }
}
