java - elasticsearch 仅按少数字段排序，并对其他字段抛出错误

Question

我有这个数据结构

{
  "id": "1777410299",
  "name": "Фий",
  "moniker": "Страна Россия, Республика Дагестан, Район Ахтынский, Село Фий",
  "fias": "b8cfa34e-465b-41c0-af72-6c03d3e08fdd",
  "macrocity": null,
  "hasMetro": false,
  "shopLink": "/stores/1777410299",
  "urlCode": "1777410299",
  "receivingMethods": [],
  "geoPoint": {
    "lat": 41.28528,
    "lon": 47.565
  },
  "kind": "Село",
  "kindShort": "с",
  "hierarchyLevels": {
    "region": {
      "id": "1775690299",
      "name": "Дагестан",
      "kind": "Республика",
      "kindShort": "Респ"
    },
    "district": {
      "id": "1777270299",
      "name": "Ахтынский",
      "kind": "Район",
      "kindShort": "р-н"
    },
    "city": null,
    "settlement": null
  }
}

我需要按经度和纬度排序，第一个元素是最接近我收到的坐标的元素

SearchRequest searchRequest = new SearchRequest()
                                    .source(SearchSourceBuilder.
                                            searchSource()
                                            .query(sourceQuery)
                                            .sort(SortBuilders.geoDistanceSort("geoPoint", lat, lon))
                                    );

这段代码给出了这个错误

此外，如果我尝试按名称字段排序(仅按 id 和 url 代码排序)

             SearchRequest searchRequest = new SearchRequest()
                                    .source(SearchSourceBuilder.
                                            searchSource()
                                            .query(sourceQuery)
                                            .sort("geoPoint.lat")
                                    );

这段代码运行良好

为什么会这样呢？我缺少什么？我该如何解决它？

Answer 1

您必须在映射中将 geoPoint 属性定义为 geo_point:

PUT deen
{
  "mappings": {
    "properties": {
      "geoPoint": {
        "type": "geo_point"
      }
    }
  }
}

PUT deen/_doc/1
{"id":"1777410299","name":"Фий","moniker":"Страна Россия, Республика Дагестан, Район Ахтынский, Село Фий","fias":"b8cfa34e-465b-41c0-af72-6c03d3e08fdd","macrocity":null,"hasMetro":false,"shopLink":"/stores/1777410299","urlCode":"1777410299","receivingMethods":[],"geoPoint":{"lat":41.28528,"lon":47.565},"kind":"Село","kindShort":"с","hierarchyLevels":{"region":{"id":"1775690299","name":"Дагестан","kind":"Республика","kindShort":"Респ"},"district":{"id":"1777270299","name":"Ахтынский","kind":"Район","kindShort":"р-н"},"city":null,"settlement":null}}

GET deen/_search
{
  "sort": [
    {
      "_geo_distance": {
        "geoPoint": {
          "lat": 41.28528,
          "lon": 47.565
        },
        "order": "asc"
      } 
    }
  ]
}

当它没有被索引为 geo_point 时，您将无法对其进行_geo_distance，就像您的异常告诉您的那样。
