elasticsearch案例：创建索引及文档请求示例

Myth丶恋晨 2023-10-14 23:13 75阅读 0赞

1、创建索引库

通过elasticsearch-head创建索引库 xc\_course，1个分片，0个副本。

2、使用postman工具创建映射，post请求：http://localhost:9200/xc\_course/doc/\_mapping

内容如下：

{
    "properties" : {
                
                "description" : {
                    "analyzer" : "ik_max_word",
    	       "search_analyzer": "ik_smart",
                   "type" : "text"
                },
                "grade" : {
                   "type" : "keyword"
                },
                "id" : {
                   "type" : "keyword"
                },
                "mt" : {
                   "type" : "keyword"
                },
                "name" : {
                    "analyzer" : "ik_max_word",
    	       "search_analyzer": "ik_smart",
                   "type" : "text"
                },
    	     "users" : {
                   "index" : false,
                   "type" : "text"
                },
    			"charge" : {
                   "type" : "keyword"
                },
                "valid" : {
                   "type" : "keyword"
                },
                "pic" : {
                   "index" : false,
                   "type" : "keyword"
                },
    		 "qq" : {
                   "index" : false,
                   "type" : "keyword"
                },
                "price" : {
                   "type" : "float"
                },
    		 "price_old" : {
                   "type" : "float"
                },
                "st" : {
                   "type" : "keyword"
                },
                "status" : {
                   "type" : "keyword"
                },
                "studymodel" : {
                   "type" : "keyword"
                },
    	    "teachmode" : {
                   "type" : "keyword"
                },
                "teachplan" : {
                    "analyzer" : "ik_max_word",
    	       "search_analyzer": "ik_smart",
                   "type" : "text"
                },
    
    	    "expires" : {
                   "type" : "date",
    		"format": "yyyy-MM-dd HH:mm:ss"
                },
    	    "pub_time" : {
                   "type" : "date",
    		 "format": "yyyy-MM-dd HH:mm:ss"
                },
    	    "start_time" : {
                   "type" : "date",
    		"format": "yyyy-MM-dd HH:mm:ss"
                },
    	   "end_time" : {
                   "type" : "date",
    		"format": "yyyy-MM-dd HH:mm:ss"
                }
             }
     }

使用postman向elasticsearch添加初始数据
