Hi Jeremiah, It does indeed not seem to be documented on the main docs site, and I will try to correct this. The only place I have found it described is on the wiki for the Ruby client (https://github.com/basho/riak-ruby-client/wiki/Secondary-Indexes). Below is also an example of a simple mapreduce job that shows how to count the number of records in the 'goog' bucket based on the $bucket secondary index:
curl -XPOST http://localhost:8098/mapred -H 'Content-Type: application/json' -d '{"inputs":{ "bucket":"goof", "index":"$bucket", "key":"goof" }, "query":[{"reduce":{"language":"erlang", "module":"riak_kv_mapreduce", "function":"reduce_count_inputs"}}]}' I hope this helps.
