## 版本
- Elasticsearch: `7.12.1`
- Kibana: `7.12.1` (if needed)
- IK Plugin: `7.12.1`
- 

## Docker创建注意

docker创建服务需要注意网关设置
```dockerfile

docker run -d --name es -e "ES_JAVA_OPTS=-Xms512m -Xmx512m" -e "discovery.type=single-node" --privileged --net esnet -p 9200:9200 -p 9300:9300 elasticsearch:7.12.1

docker run -d --name kibana -e ELASTICSEARCH_HOSTS=http://es:9200 --net esnet -p 5601:5601 kibana:7.12.1

```

## Linux创建注意

linux创建服务需要注意
参考：[this guide](https://blog.csdn.net/m0_50287279/article/details/131819482).

## 检查服务

可以获取当前服务器是否创建好
```sh
curl 127.0.0.1:9200
```
linux安装要确认好是否提供外部服务

ik分词安装注意事项
与es版本对齐，在对应的文件夹plugins创建ik文件夹，然后上传zip，解压即可；

## 创建索引

### 创建索引脚本
```sh
PUT /udi/
{
  "mappings": {
    "properties": {
      "id": {
        "type": "long"
      },
      "companyName": {
        "type": "text",
        "analyzer": "ik_max_word",
        "search_analyzer": "ik_smart"
      },
      "productFactoryCode": {
        "type": "text",
        "analyzer": "ik_max_word",
        "search_analyzer": "ik_smart"
      },
      "brandName": {
        "type": "text",
        "analyzer": "ik_max_word",
        "search_analyzer": "ik_smart"
      },
      "productName": {
        "type": "text",
        "analyzer": "ik_max_word",
        "search_analyzer": "ik_smart"
      },
      "specification": {
        "type": "text",
        "analyzer": "ik_max_word",
        "search_analyzer": "ik_smart"
      },
      "model": {
        "type": "text",
        "analyzer": "ik_max_word",
        "search_analyzer": "ik_smart"
      }
    }
  }
}
```

### 查询索引结构
```sh
GET /udi/_mapping
```

### 查询总数
```sh
GET /udi/_count
```

## 查询语句

### 查询CompanyName
```sh
POST /udi/_search
{
  "query": {
    "match": {
      "companyName": ""
    }
  }
}
```

### 查询ProductFactoryCode
```sh
POST /udi/_search
{
  "query": {
    "match": {
      "productFactoryCode": ""
    }
  }
}
```

### 规则三-转码查询
```sh
POST /udi/_search
{
  "query": {
    "bool": {
      "should": [
        {
          "match": {
            "companyName": "大博医疗"
          }
        },
        {
          "term": {
            "companyName": "大博医疗"
          }
        },
        {
          "match": {
            "productFactoryCode": "09A221013"
          }
        },
        {
          "term": {
            "productFactoryCode": "09A221013"
          }
        }
      ]
    }
  },
  "_source": ["companyName","productFactoryCode"]
}
```

### 规则四-转码查询
```sh
POST /udi/_search
{
  "query": {
    "bool": {
      "should": [
        {
          "match": {
            "productName": "/"
          }
        },

          }
        }
      ]
    }
  },
  "_source": ["productName","brandName","specification","model"]
}
```

### 分词解析预测
```sh
POST _analyze
{
  "analyzer": "ik_smart",
  "text": ["大博医疗"]
}
```
