请考虑以下的火力结构：

  {
  用户：{
    00：03：AA：DC：1C：2B：{
      名字：地平线，
      组名：泰国，
      姓氏：罗恩，
      注册 ： {
        类型：普通，
        时代：1418288589636
      }，
      phoneNumber的：345345345
    }，
    04：46：65：8D：60：C6：{
      名字：地平线，
      组名：泰国，
      姓氏：罗恩，
       注册 ： {
        类型：普通，
        时代：1418288589630
      }，
      phoneNumber的：345345345
    }，
  }
}
 

你是怎么实现下面的查询：

  SELECT * FROM用户它组名=泰国和registration.time＆GT; = 1418288589631
 

我试图做这样的：

但抛出一个异常，因为火力犯规让多个orderbys ...

任何想法？

火力地堡目前只支持每个查询单个排序依据。

因此​​，如果您要筛选（或订单）的多个属性，你要么必须做额外的滤波（或排序）客户端在你的JavaScript code或你有来与它结合了性能你自己的索引方案。

Consider following firebase structure :

{
  "users" : {
    "00:03:aa:dc:1c:2b" : {
      "firstName" : " Ofek",
      "groupName" : "thailand",
      "lastName" : "Ron",
      "registration" : {
        "type" : "regular",
        "time" : 1418288589636
      },
      "phoneNumber" : "345345345"
    },
    "04:46:65:8D:60:C6" : {
      "firstName" : " Ofek",
      "groupName" : "thailand",
      "lastName" : "Ron",
       "registration" : {
        "type" : "regular",
        "time" : 1418288589630
      },
      "phoneNumber" : "345345345"
    },
  }
}

how do you implement the following query :

SELECT * FROM USERS WHERE groupName="thailand" and registration.time>=1418288589631

I was trying to do it like this :

fireBase.orderByChild("groupName").startAt("thailand").endAt("thailand").orderByChild("time").startAt("1418288589631")

but that threw an exception since firebase doesnt allow multiple orderbys...

Any ideas?

Firebase currently only supports a single orderBy per query.

So if you want to filter (or order) on more than one property, you'll either have to do the additional filtering (or ordering) client-side in your JavaScript code or you'll have to come up with your own indexing scheme that combines the properties.
