elastic4s + elasticsearch在同一位置使用两个文档进行地理距离查询

Question

我使用Elasticsearch对地理数据进行索引，我有两个索引点;

{
  _index: "shops",
  _type: "coffee",
  _id: "2",
  _version: 73,
  found: true,
  _source: {
  location: {
    lat: 50,
    lon: 50
  },
  name: "some random cafe"
  }
}

然后我还有另外一点;

{
  _index: "shops",
  _type: "coffee",
  _id: "3",
  _version: 73,
  found: true,
  _source: {
  location: {
    lat: 50,
    lon: 50
  },
  name: "another random cafe"
  }
}

映射正确

{
  shops: {
    mappings: {
      coffee: {
        dynamic: "true",
        numeric_detection: true,
        properties: {
          location: {
            type: "geo_point",
            lat_lon: true,
            geohash: true
          },
          name: {
            type: "string",
            format: "dateOptionalTime"
          }
        }
      } 
    }
  }
}

我然后查询500公里范围内的所有点（49.9999,49.9999），我确信它在距离内;

val lat: Double = 50
val lat: Double = 49.9999
val dist: String = "500km"
client execute {
      search in “shops" -> “coffee" filter {
        and (
          geoDistance("location") point(lat, lon) distance dist,
          or(modelIdTerms:_*)
        )
      } sourceInclude(“name")
    } await

只给我一击。通过curl完全相同的查询给了我两个点击。这可能是Elastic4s的一个错误吗？
