Riak search returning "No index" and "(23) Failed writing body"

I have a test system and I've created and activated libraries as a search property on the bucket type clients. 

➜  riak-2.1.0  curl http://localhost:8098/buckets/coding-with-riak/props
{"props":{"allow_mult":false,"basic_quorum":false,"big_vclock":50,"chash_keyfun":{"mod":"riak_core_util","fun":"chash_std_keyfun"},"dvv_enabled":false,"dw":"quorum","last_write_wins":false,"linkfun":{"mod":"riak_kv_wm_link_walker","fun":"mapreduce_linkfun"},"n_val":3,"name":"coding-with-riak","notfound_ok":true,"old_vclock":86400,"postcommit":[],"pr":0,"precommit":[],"pw":0,"r":"quorum","rw":"quorum","search_index":"libraries","small_vclock":50,"w":"quorum","write_once":false,"young_vclock":20}}%

I believe I set the bucket, coding-with-riak, in a way that makes it ready for search: 

➜  ~  curl http://localhost:8098/buckets/coding-with-riak/props
{"props":{"allow_mult":false,"basic_quorum":false,"big_vclock":50,"chash_keyfun":{"mod":"riak_core_util","fun":"chash_std_keyfun"},"dvv_enabled":false,"dw":"quorum","last_write_wins":false,"linkfun":{"mod":"riak_kv_wm_link_walker","fun":"mapreduce_linkfun"},"n_val":3,"name":"coding-with-riak","notfound_ok":true,"old_vclock":86400,"postcommit":[],"pr":0,"precommit":[],"pw":0,"r":"quorum","rw":"quorum","search_index":"libraries","small_vclock":50,"w":"quorum","write_once":false,"young_vclock":20}}%

But when I try to search, through the Ruby client or through cURL, it errors: 

>> coding.keys
Riak::Bucket#keys is an expensive operation that should not be used in production.
=> ["ruby", "python", "go"]
>> results = client.search("coding-with-riak", "maintainer_s:*")
Riak::ProtobuffsErrorResponse: Expected success from Riak but received 0. No index <<"coding-with-riak">> found.

cURL has similar results: 

➜ curl "http://localhost:8098/search/query/libraries?wt=json&q=popular_b:true"
(23) Failed writing body

What did I miss? I've walked through the search how-to more than a few times and can't find what I'm missing. Note that I did reboot after activating the search properties.

Solution

  • The kind folks on #riak IRC corrected both problems, which are different.

    On the ruby side, I need to supply the search index, not the bucket: 

    >> results = client.search("libraries", "maintainer_s:basho")
=> {"max_score"=>1.8109302520751953, "num_found"=>1, "docs"=>[{"score"=>"1.81093030000000010382e+00", "_yz_rb"=>"coding-with-riak", "_yz_rt"=>"default", "_yz_rk"=>"ruby", "_yz_id"=>"1*default*coding-with-riak*ruby*56", "name_s"=>"Ruby Client", "maintainer_s"=>"basho", "popular_b"=>"true"}]}

    And for cURL queries, I was having an encoding issue due to my host file mapping of localhost as used above. Using 127.0.0.1 worked:

    ➜  ~  curl "http://127.0.0.1:8098/search/query/libraries?wt=json&q=popular_b:true" | json_pp
