Hello Xiaopong, Apologies about the trouble you had with the Erlang client. I'll run through the client docs on Monday and make sure we have everything properly explained.
While we're on the topic of Erlang client documentation, you might find these handy - http://basho.github.com/riak-erlang-client/ (We are now using GitHub as the canonical home for Riak code but the BitBucket mirror is in place and working so if that's what you prefer, you'r all good.) We generated the docs about two weeks back (we're actually in the process of doing these for all the Riak clients) so they might be _slightly_ behind what is in master, but I thought they couldn't hurt to share). Hope they help. We'll check out the docs (and regenerate as needed) once Monday comes around. Thanks for diving into Riak.
