Question

我在firebase中有相对大量的数据：https://nysenate.firebaseio.com/

问题是如何按顺序获得结果。

例如，对于100K对象的firebase，我希望在整个集合按publishedDateTime排序后得到前10个。

但是如果你看结果，它似乎根本没有排序。事实上，我无法真正说出订单是什么。

（这些都是公共读取的火灾基础，因此您可以使用相同的curl命令进行测试）

$ curl 'https://nysenate.firebaseio.com/bills.json?orderBy="publishedDateTime"&limitToFirst=10&print=pretty' |grep publishedDateTime
   "publishedDateTime" : "2015-06-05T09:16:05",
   "publishedDateTime" : "2015-06-05T09:16:05",
   "publishedDateTime" : "2015-06-05T09:21:05",
   "publishedDateTime" : "2015-06-05T09:21:05",
   "publishedDateTime" : "2015-06-05T11:21:11",
   "publishedDateTime" : "2015-06-05T10:36:09",
   "publishedDateTime" : "2015-06-05T13:56:18",
   "publishedDateTime" : "2015-06-05T11:16:11",
   "publishedDateTime" : "2015-06-05T13:51:18",
   "publishedDateTime" : "2015-06-05T13:46:18",

它似乎适用于少量数据:( 6个物体）使用其中一个示范火焰基地。

$ curl 'https://dinosaur-facts.firebaseio.com/dinosaurs.json?orderBy="height"&limitToFirst=10&print=pretty' |grep height
            "height" : 0.6,
            "height" : 0.6,
            "height" : 2.1,
            "height" : 3,
            "height" : 4,
            "height" : 25,
