Mongo DB在Rockmongo中查找查询

Question

Very simple question, trying to run some simple queries in the "execute" part of rock mongo i have this function

function () {
var bla = db.login.find({userData: {userId:'12339'}}).count();
return bla;
}

the response is correct { "retval": 2, "ok": 1 }

if i remove the .count() in the end and make the function like this

function () {
var bla = db.login.find({userData: {userId:'12339'}});
return bla;}

the response is

{
   "retval": {
     "value": "DBQuery: bet.login -> undefined" 
  },
   "ok": 1 
}

Can any one help me perform a simple find...
