一、索引

1、创建索引

• 请求方式：PUT
• 请求路径：索引库名
• 请求参数：json格式

PUT goods
{
  "settings": {
    "number_of_shards": 1,
    "number_of_replicas": 0
  }
}

settings: 索引库的设置
number_of_shards：分片数量
number_of_replicas：副本数量

2、查看索引

GET goods
结果：
{
  "goods": {
    "aliases": {},
    "mappings": {},
    "settings": {
      "index": {
        "creation_date": "1576352109034",
        "number_of_shards": "1",
        "number_of_replicas": "0",
        "uuid": "Gj7xO8mWR7qJTLveA7s73Q",
        "version": {
          "created": "6020499"
        },
        "provided_name": "goods"
      }
    }
  }
}

3、查询所有索引

GET *

4、删除索引

DELETE goods

二、映射

映射是定义文档的过程，文档包含哪些字段，这些字段是否保存，是否索引，是否分词等

1、创建映射字段

PUT goods/_mapping/course
{
  "properties": {
    "title": {
      "type": "text",
      "analyzer": "ik_max_word"
    },
    "images": {
      "type": "keyword",
      "index": false
    }
  }
}

2、查看映射关系

GET goods/_mapping

-- 结果 --
{
  "goods": {
    "mappings": {
      "course": {
        "properties": {
          "images": {
            "type": "keyword",
            "index": false
          },
          "title": {
            "type": "text",
            "analyzer": "ik_max_word"
          }
        }
      }
    }
  }
}
