Riak 搜索给我“未找到”可用数据错误
我已经在 Ubuntu Natty 上安装了 Riak 1.0.2。
我还在数据库中添加了一些示例数据。我使用 LevelDB 后端是因为我想测试二级索引功能。
我添加了一个 test_1 存储桶。我向该存储桶添加了以下信息。
array("name" => "Ray_6", "age" => rand(25, 90), "email" => "[email protected]") with key "id_1"
array("name" => "Ray_7", "age" => rand(25, 90), "email" => "[email protected]") with key "id_2"
array("name" => "Ray_8", "age" => rand(25, 90), "email" => "[email protected]") with key "id_3"
我正在尝试使用搜索功能来查询此数据。以下是我在命令行中输入的 CURL 请求：
curl http://localhost:8098/solr/test_1/select?q=name:Ray_6
但是当我执行此操作时，我收到“未找到”错误。
我有什么遗漏的吗？我是否应该对存储桶做一些事情以使其可搜索？
我希望得到一些帮助。
提前致谢。
I've installed Riak 1.0.2 on Ubuntu Natty.
I have also added some sample data to the database. I'm using a LevelDB backend because I want to test the Secondary Indexing functionality.
I added a test_1 bucket. And to that bucket I added the following information.
array("name" => "Ray_6", "age" => rand(25, 90), "email" => "[email protected]") with key "id_1"
array("name" => "Ray_7", "age" => rand(25, 90), "email" => "[email protected]") with key "id_2"
array("name" => "Ray_8", "age" => rand(25, 90), "email" => "[email protected]") with key "id_3"
I'm trying to use the Search feature to query this data. Below is the CURL request that I enter into the command line:
curl http://localhost:8098/solr/test_1/select?q=name:Ray_6
But when I do this, I get a no found error.
Is there something I'm missing? Am I supposed to do something to the bucket to make it searchable?
I'd appreciate some assistance.
Thanks in advance.

嗯，首先，上面的 URL 使用的是 Riak Search，而不是二级索引。查询二级索引的URL形式为：
通过cURL接口创建记录时，添加元数据头，形成二级索引。不同语言的客户端库将为您生成此内容。
不过，回到你的具体问题。您是否使用 search-cmd 工具为 test_1 存储桶安装索引？如果您这样做了，那么在这样做之前您的存储桶中是否有数据？ Riak Search 不会追溯索引您的数据。有几种方法可以做到这一点，但如果这只是一个实验性应用程序，那么这两种方法都很耗时。
如果你的数据不多，建议你设置好索引后重新输入。否则，您需要在读/写一条数据时添加二级索引或通过搜索API进行处理。这需要时间，但现在可以通过 Riak 获得。
希望这有帮助。
Well, firstly, the above URL is using Riak Search and not the secondary indexes. The URL to query a secondary index is in the form of:
You form a secondary index by adding metadata headers when creating a record through the cURL interface. Client libraries for different languages will generate this for you.
Back to your specific question, though. Did you use the search-cmd tool to install an index for the test_1 bucket? If you did, did you have data in the bucket before doing so? Riak Search will not retroactively index your data. There are a few ways available to do so, but both are time-consuming if this is just an experimental app.
If you don't have much data, I suggest you re-enter it after setting up the index. Otherwise, you need to add secondary index or process it through the search API as you read/write a piece of data. It'll take time, but it's what is available through Riak now.
Hope this helps.
