As in console you use:
db.test.find({"user.nick" : "joy.cood"}, {"user.email" : true})
in mongodb-erlang you should use:
mongo:find_one(Pid, <<"test">>,{<<"user.nick">>, <<"joy.cood">>}, {<<"user.email">>, true}).
The result will be:
{{'_id',{<<85,168,179,145,8,33,209,140,53,194,18,19>>},
user,
{email,<<"[email protected]">>}}}
from mongodb-erlang.
