Hi Izhar, I've included a command-line example below that uses the special $key field.
Note that on the command line, the dollar sign ($) must be escaped with a backslash, otherwise the shell thinks you are referencing a variable. You won't need to escape the dollar sign using the client libraries. Best, Rusty ## Load some data... curl -v -X PUT -d 'data1' -H "x-riak-index-field1_bin: val1" \ http://127.0.0.1:8098/riak/bucket1/key1 curl -v -X PUT -d 'data2' -H "x-riak-index-field1_bin: val2" \ http://127.0.0.1:8098/riak/bucket1/key2 curl -v -X PUT -d 'data3' -H "x-riak-index-field1_bin: val3" \ http://127.0.0.1:8098/riak/bucket1/key3 curl -v -X PUT -d 'data4' -H "x-riak-index-field1_bin: val4" \ http://127.0.0.1:8098/riak/bucket1/key4 curl -v -X PUT -d 'data5' -H "x-riak-index-field1_bin: val5" \ http://127.0.0.1:8098/riak/bucket1/key5 ## Run a REST-based query. In a web browser, you can just open http://localhost:8098/buckets/bucket1/index/$key/key2/key4 curl http://localhost:8098/buckets/bucket1/index/\$key/key2/key4 ## Run a M/R-based query... curl -X POST \ -H "content-type: application/json" \ -d @- \ http://localhost:8098/mapred \ <<EOF { "inputs":{ "bucket":"bucket1", "index":"\$key", "start":"key2", "end":"key4" }, "query":[ { "reduce":{ "language":"erlang", "module":"riak_kv_mapreduce", "function":"reduce_identity", "keep":true } } ] } EOF On Thu, Dec 15, 2011 at 11:06 AM, Izhar Ravid <iz...@conduit.com> wrote: > HI All, > > The Basho wiki states that: > The $key index field is a special field that is implicitly indexed on all > objects when Secondary Indexes is enabled.
