ElasticSearch添加索引

  

1. 编写索引内容

  节点解释:

  settings:配置信息

  "number_of_replicas": 0  不需要备份(单节点的ElasticSearch使用)

  "mappings":  映射内容

  "dynamic":false  是否动态索引,这里使用的是false,表示索引的固定的,不需要修改。

  "properties": 属性结构内容

  "index":"true"  需要分词处理的结构

  type对应的数据类型,text文本(长字符串),integer数字,date时间,keyword单词

 

elasticsearch 6.X版本的索引文件

{
  "settings":{
    "number_of_replicas": 0
  },
  "mappings":{
    "house":{
      "dynamic":false,
      "properties":{
        "houseId":{"type":"long"},
        "title":{"type":"text", "index":"true"},
        "price":{"type":"integer"},
        "area":{"type":"integer"},
        "createTime":{"type":"date","format":"strict_date_optional_time||epoch_millis"},
        "lastUpdateTime":{"type":"date", "format":"strict_date_optional_time||epoch_millis"},
        "cityEnName":{"type":"keyword"},
        "regionEnName":{"type":"keyword"},
        "direction":{"type":"integer"},
        "distanceToSubway":{"type":"integer"},
        "subwayLineName":{"type":"keyword"},
        "subwayStationName":{"type":"keyword"},
        "tags":{"type":"text"},
        "district":{"type":"keyword"},
        "description":{"type":"text", "index":"true"},
        "layoutDesc":{"type":"text", "index":"true"},
        "traffic":{"type":"text", "index":"true"},
    "roundService": {"type": "text", "index": "true"},
        "rentWay":{"type":"integer"}
      }
    }
  }
}

 

elasticsearch 7.X版本的索引文件

{
  "settings":{
    "number_of_replicas": 0
  },
  "mappings":{
    "dynamic":false,
    "properties":{
      "title":{"type":"text", "index":"true"},
      "price":{"type":"integer"},
      "area":{"type":"integer"},
      "createTime":{"type":"date","format":"strict_date_optional_time||epoch_millis"},
      "lastUpdateTime":{"type":"date", "format":"strict_date_optional_time||epoch_millis"},
      "cityEnName":{"type":"keyword"},
      "regionEnName":{"type":"keyword"},
      "direction":{"type":"integer"},
      "distanceToSubway":{"type":"integer"},
      "subwayLineName":{"type":"keyword"},
      "subwayStationName":{"type":"keyword"},
      "tags":{"type":"text"},
      "district":{"type":"keyword"},
      "description":{"type":"text", "index":"true"},
      "layoutDesc":{"type":"text", "index":"true"},
      "traffic":{"type":"text", "index":"true"},
   "roundService": {"type": "text", "index": "true"},
      "rentWay":{"type":"integer"}
    }
  }
}

 

2. 创建索引

  使用Postmen发送创建索引请求

  (1)地址栏后半段是索引名称

  (2)请求使用的PUT方式,选择Body,raw形式,采用JSON格式发送

  创建成功的显示结果:

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

  在ElasticSearch-Head里查看结果:

 

3. 创建索引时的报错:

  错误1:Root mapping definition has unsupported parameters

  原因:ElasticSearch7.X之后的版本默认不在支持指定索引类型,默认索引类型是_doc(隐含:include_type_name=false),所以在mappings节点后面,直接跟properties就可以了。

  

  问题2:Could not convert [title.index] to boolean

  原因:也是新版本的问题,之前版本的index属性写法是"analyze",现在只能设置true, false, "true","false"
