Elasticsearch Bridge和MongoDB IndexAlreadyExist具有自定义映射

因为有几天我遇到了无法解决的问题：

我想要发生的事情：我有一个集合，应该通过https://github.com/richardwilly98/elasticsearch-river-mongodb bevor转移到elasticsearch我创建河流我设置索引的自定义映射，这样我就不会得到动态映射，我可以在elasticsearch中使用geo_point类型 .

所以首先是Mongodb的蒙德尔：

screenName: { type: String, required: true, unique: true, sparse: true },
firstName: { type: String, validate: isString, index: true },
lastName: { type: String, validate: isString, index: true },
deleted: { type: Number, index: true, default: 0 },
homeBase: {
    type: {
        type: String,
        default: 'Point'
    },
    coordinates: [Number] // [<longitude>, <latitude>]
},
realTime: {
    type: {
        type: String,
        default: 'Point'
    },
    coordinates: [Number] // [<longitude>, <latitude>]
}

RealTime和homeBase是2dSpheres

预映射

{
"settings": {
    "mapper": {
        "dynamic": false
    }
},
"mappings": {
    "default": {
        "properties": {
            "firstName": {
                "type": "string"
            },
            "lastName": {
                "type": "string"
            },
            "screenName": {
                "type": "string"
            },

            "homeBase": {
                "type": "object",
                "properties": {
                    "coordinates": {
                        "type": "geo_point"
                    }
                }
            },
            "realTime": {
                "type": "object",
                "properties": {
                    "coordinates": {
                        "type": "geo_point"
                    }
                }
            }
        }
    }
}

Wich也运行良好，并获得索引Url调用PUT localhost：9200 / users

现在是河

{
"type": "mongodb",
"mongodb": {
  "servers": [
    {
      "host": "localhost",
      "port": "27017"
    }
  ],
  "options": "drop_collection",
  "db": "entities",
  "collection": "users"
},
"index": {
  "name": "users",
  "type": "documents"
}
}

在这里我打电话给PUT http://localhost:9200/_river/users/_meta我收到的是{"error"："IndexAlreadyExistsException[[users] already exists]"，"status"：400}

我需要什么？做像这样的查询

GET _search
{
"query": { 
"filtered": {
   "query": {
       "multi_match": {
                                "query": "mario",
                                "fields": ["firstName", "lastName",     "specialities"]
                            }
    },
    "filter" : {
        "mutate" {
         "convert" => { "homeBase.coordinates" => "geo_point"}   
        },
        "geo_bounding_box" : {
            "homeBase.coordinates" : {
                "top_left" : [1,100],
                "bottom_right" : [1,100]
            }
        }
    }
}
}
}

标准我如何得到位置字段是一个双，如果有人知道一种方法来查询双打坐标周围的位置它也没关系 .

请帮忙！
