How did you add an index to the object? A header of 'X-Riak-Meta-All' suggests
that you added some user meta, I would hope to see a header like
'x-riak-index-all_int' in the response. You can add a secondary index like this
curl -X POST -H 'x-riak-index-all_int: 2' -d 'YOUR DATA'
http://localhost:8071/buckets/YOUR_BUCKET/keys/YOUR_KEY

Your query looks right. You can read more on the Basho wiki here[1] and here[2]
