Hagbard,
what the Protobufs client (which I assume is what you're using) does to get
search results is to run a MapReduce job with the search as input.
You can easily use this to your advantage to achieve what you're after with a
custom map function, example to follow. When Riak Search results are fed into
the map phase, it receives the score in the keydata parameter, so you can just
use an anonymous function to return both the Riak object and the key data, or
extract the just score, as you see fit for your use case.
MapObjectKeydata = fun(RiakObject, KeyData, none) ->
[RiakObject, KeyData]
end.
Timeout = 100000.riakc_pb_socket:search(Pid, "bucket", "query", [{map, {qfun,
MapObjectKeydata}, none, true}], Timeout).
