Hi Daniel, Have a look at this page: http://docs.basho.com/riak/latest/dev/references/protocol-buffers/secondary-indexes/
'return_terms' is a flag you can pass true or false for. It ensures that you get the value of the index as well as the associated key with your result set, which can make it easier to group or sort on the client-side. 'term_regex' is a quasi-PCRE that is used to additionally filter the index as it's being traversed. NHS requested and submitted the code for this feature because they found that it greatly improved query speed in their use-case; their index terms were very regular but needed to support wildcards and such. Also, at the time they were developing, Riak Search 2 (Yokozuna) was not ready. Your mileage may vary.
