Is it possible to re-order view values by using map reduce?

Question

I need to reorder the coiuchbase views results based on the values.I am writing a map reduce like below and did sorting using group, reduce and descending keys.

function (doc, meta) {
 if(doc.transactionType=='Transaction') 
  {
    for(var i=0; i<doc.transactionList.length; i++)  
     {  
         if(doc.transactionList[i].bucket==1)  { 
          emit(doc.transactionList[i].transactionId,null);
         }
     } 
  } 
}

Reduce= _count I got the result the way i was expecting. I know couchbase views filter on the basis of keys only.

{"rows":[
  {"key":"Transaction1","value":2},
  {"key":"Transaction3","value":3},
  {"key":"Transaction4","value":1}
  ] 
}

Is it possible to get the below results. If so, any advice what I am missing here?

{"rows":[
    {"key":"Transaction3","value":3},
    {"key":"Transaction1","value":2},
    {"key":"Transaction4","value":1}
  ]
}

No, you can not sort by value in couchbase. Only by key You should sort before inserting or after requesting data from view
