我的弹性查询中出错 - 范围返回错误的请求

我有以下函数可以进行弹性搜索：

$scope.getLocationHistory = function(device, lastTime){
    console.log("Device location searching");
    query = {
        "query": {
            "bool": {          
                "must": [
                    { "term": {"deviceId":device} },
                    { "match": {"eventType":"Connected"} } 
                ],
                "must_not":[
                    {"query_string": {
                            "query": "Pong",
                            "fields": ["data.message"]
                        }
                    },
                ] 
            }                  
        },
        "range" : {
            "timestamp" : {
                "gt" : "now-1h"
            }
        },
        "filter" : {
            "exists" : { "field" : "data.location" }
        },
        "sort": [{ "timestamp": { "order": "desc" }}]
    }
    $http.post(databaseLocation+"/canary/_search", query).success(function(data, status, headers, config){
        $scope.getMapHistory(data.hits.hits); //Auxiliary function
    }).error(function(data, status, headers, config){
        console.log(data);
    }); 
}

我是弹性查询的新手，我在范围字段上收到此错误：

POST http://... 400 (Bad Request) Object {error: "SearchPhaseExecutionException[Failed to execute ph…arse Failure [No parser for element [range]]]; }]", status: 400}error: "SearchPhaseExecutionException[Failed to execute phase [query], all shards failed;....

可能我写错了范围字段，但我发现了如何在此文档中使用它：www.elasticsearch.org/...

我想知道我在查询上做错了什么。
