Couchbase strange view behavior with keys with zero - couchbase

Question

I hava a database, that contains chat messages between users (1 message copy per user: 1 message for sender and one for recepient). Running Couchbase server 2.0 cluster with 2 machines (1 linux and 1 windows).
I use such map function to retreive messages betwen users:
function (doc) {
if (doc.type == "msg"){
emit([doc.OwnerId, doc.SndrId, doc.Date], {"Date":doc.Date, "OwnerId":doc.OwnerId, "RcptId":doc.RcptId, "SndrId":doc.SndrId, "Text":doc.Text, "Unread":doc.Unread, "id": doc.id, "type":doc.type});
emit([doc.OwnerId, doc.RcptId, doc.Date], {"Date":doc.Date, "OwnerId":doc.OwnerId, "RcptId":doc.RcptId, "SndrId":doc.SndrId, "Text":doc.Text, "Unread":doc.Unread, "id": doc.id, "type":doc.type});
}
}
So if I try to receive some messages (ordered decending by date) from the beggining I used such startkey & endkey:
startkey=[1,2,{}]
endkey=[1,2,0]
But in this way I get not all messages. To get all messages I need to use
startkey=[1,2,{}]
endkey=[1,2]
Here is an example. For key with zero:
{"total_rows":1106,"rows":[
{"id":"msg_8aaca454-5580-4e49-a081-918d8eaba9d6","key":[8,75,1342200837278],"value":{"Date":1342200837278,"OwnerId":8,"RcptId":8,"SndrId":75,"Text":"02","Unread":false,"id":"8aaca454-5580-4e49-a081-918d8eaba9d6","type":"msg"}},

]
}
Can anyone explain why it not binds all messages in first case?

Answer 2

NB CouchDB and CouchBase are as similar as Membase and MySQL = products that start with the same prefix. Best not to get them confused!
It might be related to whether sorting is done via ASCII (what you are expecting) vs via unicode collation. Some more information here http://wiki.apache.org/couchdb/View_collation but that applies to CouchDB, not CouchBase. Maybe that helps?
