Hi Carson,
You are definitely on the right track. The SearchQuery parameter is a
Lucene-syntax-ish search query, and the Bucket parameter is the bucket on
which to search. You can find more information on the query syntax here:
http://wiki.basho.com/display/RIAK/Riak+Search+-+Querying
Usage is as follows:
{ok, Pid} = riakc_pb_socket:start("127.0.0.1", "8087"),
Bucket = "json",
SearchQuery = "firstname:John"),
{ok, BucketKeyList} = riakc_pb_socket:search(Pid, Bucket, SearchQuery,
riakc_pb_socket:stop(Pid).
You can also do more complicated things like using the results to spawn a
map/reduce operation by adding a MapReducePhases parameter. You can find
more information on map/reduce phases here:
http://wiki.basho.com/display/RIAK/MapReduce
{ok, Result} = riakc_pb_socket:search(Pid, "json", "firstname:John",
MapReducePhases, TimeoutInMS),
Best,
Rusty
