Question

我是ElasticSeach的新手，我已经在弹性群集中索引了一系列城市。每个城市都包含城市，州，地点（纬度和长度）等详细信息。

现在我的要求是搜索特定地点20公里范围内的城市，我正在通过纬度和特定城市的城市已被索引到集群中。

以下是我在弹头搜索头部插件的UI中显示的索引数据：

{
    "_index": "us_large_cities",
    "_type": "city",
    "_id": "AVqDpwkjfjWoT7yVe_qt",
    "_version": 1,
    "_score": 1,
    "_source": {
        "city": "Lincoln",
        "state": "NE",
        "location": {
            "lat": "40.8000011",
            "lon": "-96.6669599"
         }
     }
}

这是我用于搜索数据的curl命令：

curl -XGET 'http://localhost:9200/us_large_cities/city/_search?pretty=true' -d '
{
  "query": {
    "filtered" : {
        "query" : {
            "match_all" : {}
        },
        "filter" : {
            "geo_distance" : {
                "distance" : "20km",
                "location" : {
                    "lat" : 40.8000011,
                    "lon" : -96.6669599
                }
            }
        }
    }
  }
}'

我得到了SearchParseException，这里是完整的堆栈跟踪：

    "filtered" : {

        "filter" : {
            "geo_distance" : {
                "distance" : "20km",
                "location" : {
                    "lat" : 40.8000011,
                    "lon" : -96.6669599
                }
            }
        }
    }
  }
}]]

我搜索了SO中可能出现的各种帖子，但没有一个对我有用。我有错误的任何建议吗？

Answer 1

[us_large_cities] failed to find geo_point field [location]

这是您的错误，因为如果您要使用geo_distance过滤器，则必须将位置字段编入索引为geo_point字段。更多信息here。

编辑：所以

"location": {
            "lat": "40.8000011",
            "lon": "-96.6669599"
         }

需要定义为：

{
    "city_location" : {
        "location" : {
            "lat" : 41.12,
            "lon" : -71.34
        }
    }
}
