Riak 搜索返回“No index”和“(23) Failed writing body”

Question

我有一个测试系统，我创建并激活了libraries 作为存储桶类型clients 的搜索属性。

➜  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}}%

我相信我设置了存储桶coding-with-riak，使其准备好进行搜索：

➜  ~  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}}%

但是当我尝试通过 Ruby 客户端或通过 cURL 进行搜索时，它会出错：

>> 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 也有类似的结果：

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

我错过了什么？我已经多次浏览search how-to，但找不到我缺少的东西。请注意，我在激活搜索属性后确实重新启动了。

#riak IRC 上的好心人纠正了这两个不同的问题。

在 ruby​​ 方面，我需要提供搜索索引，而不是存储桶：

>> 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"}]}

对于 cURL 查询，由于上面使用的 localhost 的主机文件映射，我遇到了编码问题。使用127.0.0.1 工作：

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