elasticsearch - 地理距离过滤器

Question

我收到来自 elasticsearch 的 400 错误请求错误。错误是一个大块响应，但我相信这是关键部分。

failed to find mapper for [location] for geo distance based sort

我正在使用 ES 1.5.1 来查询。我的查询是:

{
  query: {
    filtered: {
      query: {
        match: {
          title:"amsterdam*"
        }
      }
    }
  }, sort: [
       {
         _geo_distance: {
           location: {lat:0, lon:0}, order:"asc", unit:"miles"
         }
       }
     ]
}

我已经像文档一样格式化了查询 here .我错过了一步吗？

这是我当前的映射:

{
  "gb": {
    "mappings": {
      "store": {
        "dynamic":"false",
        "properties": {
          "active": {
            "type": "b‌​oolean"
          },
          "deleted": {
            "type": "boolean"
          },
          "location": {
            "type":"geo_point"
          },
          "open": {
            "ty‌​pe": "boolean"
          },
          "suspended": {
            "type": "boolean"
          },
          "title": {
            "type":"string"
          }
        }
      }
    }
  }
}

您的查询很好。字段 location 必须具有映射类型 geo_point，它似乎具有。

试试这个 Marvel Sense 脚本:

(通过运行 bin/plugin -i elasticsearch/marvel/latest 安装 Marvel)

put geo
put geo/geo/_mapping
{
  "properties": {
    "location": {
          "type": "geo_point",
          "geohash" : true
    }
  }
}
put geo/geo/1
{
  "location": {
    "lat": 0.1,
    "lon": 0.1
  }
}
put geo/geo/2
{
  "location": {
    "lat": 50.1,
    "lon": 7.1
  }
}
put geo/geo/3
{
  "location": {
    "lat": 5.1,
    "lon": 3.1
  }
}
get geo/geo/_search
{
  "query": {
        "match_all": {
        }
    }, 
  "sort": [
       {
         "_geo_distance": {
           "location": {"lat":0, "lon":0}, 
           "order":"asc", 
           "unit":"km"
         }
       }
     ]
}
get geo/_mapping

出于某种原因，Sense 中的搜索查询对我不起作用。通过 curl 它可以正常工作:

curl -XGET '0:9200/geo/geo/_search?pretty' -d@query.json
