CouchDB复杂关键视图未按预期返回结果

Question

我正在使用CouhDB 1.1 - 我正在尝试：

SELECT doc.data WHERE doc._id="c" order by doc.date

我有以下3个文档：

{
   "_id": "c",
   "_rev": "7-4193c63ab034214ff5514006ac1143b2",
   "data": "c",
   "date": "2009/01/01"
}

{
   "_id": "b",
   "_rev": "3-9200b985d55a8f778d9726d6f1e9dbe0",
   "data": "b",
   "date": "2010/01/01"
}

{
   "_id": "a",
   "_rev": "4-2834579ebc10e0467191bf9c8f115b60",
   "data": "a",
   "date": "2011/01/01"
}

以下视图来查询它：

function(doc) {
  emit([doc.data, doc.date], doc._id); 
}

我发送以下查询：

http://localhost:5984/tryme/_design/view/_view/data?key=[{},"c"]&descending=true

返回0个文档

和

http://localhost:5984/tryme/_design/view/_view/data?startkey=[{},"c"]&descending=true

返回所有文档...

我假设这应该有效，基于此：translate this mysql into a couchdb view?
