1、查询有哪些索引

GET _cat/indices

2、创建索引同时定义映射

PUT /tb_student
PUT /tb_student
{
  "mappings": {
    "properties": {
      "studentId" : {
        "type": "keyword"
      },
      "userName": {
        "type": "text",
        "analyzer": "ik_smart"
      },
      "hobby": {
        "type": "text",
        "analyzer": "ik_max_word"
      },
      "gender": {
        "type": "keyword"
      },
      "age": {
        "type": "integer"
      },
      "className": {
        "type": "keyword"
      },
      "createTime" : {
        "type": "date",
        "format": "yyyy-MM-dd HH:mm:ss"
      }
    }
  }
}

3、删除索引

DELETE /tb_student

4、查看索引信息

GET /tb_student

5、添加一条记录到索引中

PUT /tb_student/_doc/1
{
  "userId": 1,
  "userName": "李玉坤",
  "gender": "男",
  "age": 18,
  "className": "一年级2班",
  "hobby": "打羽毛球,打蓝球，游泳",
  "createTime": "2024-01-13 11:12:22"
}

6、查询所有记录

GET /tb_student/_search
{
  "query": {
    "match_all": {}
  }
}
