Hi, to close this thread, I wrote a very brief blog post documenting basic
usage of secondary indices and get_index using riakc at
http://www.jeremyong.com/blog/2012/07/23/secondary-indices-in-riak-with-erlang/
It's obviously not geared toward expert users (I for one, am not an expert
user) but I'm throwing it out there in case somebody else struggles with
the same issues.
Cheers,
Jeremy
