mongodb - Robomongo, how to use custom functions? -

i'm trying use mongodb client "robomongo" http://robomongo.org/

it works fine, can't understand how access functions created on "functions" section...

i want test mapreduce functionality, i've created map() , reduce() function, when write on shell:

db.<name_of_collection>.mapreduce(map, reduce, {out: {inline: 1}}); 

robomongo give me following error:

referenceerror: map not defined (shell):1 

---

i've tried this:

db.<collection_name>.mapreduce(db.system.js.map, db.system.js.reduce, {out: {inline: 1}}); 

but again, seems wrong...

uncaught exception: map reduce failed:{     "errmsg" : "exception: javascript execution failed: referenceerror: learn not defined",     "code" : 16722,     "ok" : 0 } 

you can access stored functions in several ways:

1)

db.collection.mapreduce(     "function() { return map(); }",      "function(key, values) { return reduce(key, values); }",     {out: {inline: 1}}); 

2)

db.collection.mapreduce(     function() { return map(); },      function(key, values) { return reduce(key, values); },     {out: {inline: 1}}); 

note using functions now, not strings in 1)

3)

if using mongodb 2.1 or above, can do:

db.loadserverscripts(); db.collection.mapreduce(     map,      reduce,     {out: {inline: 1}});

robomongo use same engine used mongodb shell. questions mongodb, not robomongo.
