sorting - Elasticsearch _geo_distance排序错误

Question

问候过花，

为什么我使用官方的nodejs客户端通过Elasticsearch(1.2.2)收到此错误？

Parse Failure [No mapping found for [[object Object]] in order to sort on]]
"sort":[{"_score":{}},{"[object Object]":{}}]

这是我的查询(JSON格式):

{
    "index":"myidx",
    "type":"mytype",
    "body":{
        "query":{
             "filtered":{
                  "filter":{
                      "and":[
                          {"term":{"to":"WORLD"}},
                          {"or":[
                              {"term":{"invisible":false}},
                              {"term":{"user":"@geeko"}}
                          ]},
                          {"term":{"blocked":false}}
                      ]
                  },
                  "query":{"terms":{"text":["world"]}}
             }
        }
    },
    "sort":[
        "_score",
        {"_geo_distance":{"mytype.location":"0.0,0.0"}}
    ],
    "from":0,
    "size":20
}

顺便说一句，我所有的映射都已定义(特别是mytype.location是geo_point)，并且如果删除_geo_distance排序，此查询将起作用。

亲切的问候

更新(映射和示例):

{
    "template": "myidx",
        "mytype": {
            "dynamic": "strict",
            "properties": {
                "id": {"type": "long"},
                "timestamp": {
                    "type": "date",
                    "format": "date_time"
                },
                "location": {"type": "geo_point"},
                "user": {
                    "type": "string",
                    "index": "not_analyzed"
                },
                "text": {
                    "type": "string",
                    "analyzer": "simple"
                },
                "to": {
                    "type": "string",
                    "index": "not_analyzed"
                },
                "invisible": {"type": "boolean"},
                "blocked": {"type": "boolean"}
            }
        }
    }
}

{
    "id":"1",
    "timestamp":"2014-08-07T20:35:40.936Z",
    "location":"10.0,10.0",
    "user":"@geeko",
    "text":"Hello World!",
    "to":"WORLD",
    "invisible":false,
    "blocked":false
}

Answer 1

实际上，这是由于我对nodejs客户端使用不当造成的。
我使用的是客户端搜索功能提供的sort属性(这相当于不接受_geo_distance之类的URL中排序)，我应该在查询主体中使用sort属性。
