如何让狮身人面像实时索引？

Question

我有一个Rails 3.2.6应用程序，我使用的是Sphinx 0.9.9和Thinking Sphinx 2.0.12。

我需要Sphinx实时更新其索引。例如，当用户创建新帖子时，它会立即显示在搜索结果中。或者，如果他们删除了一条信息，它就不会显示，从删除它的时刻开始。

我跟着关于delta indexing的文档。

在此基础上建议，我有一个执行每二十分钟，运行bundle exec rake ts:index RAILS_ENV=production cron作业...

打开增量索引不会删除需要定期运行完全重新索引，否则三角洲指数本身将会变得和核心指数一样大，这就消除了保持分离的优势。它还会减慢对服务器的更改模型记录的请求。

只有在作业运行后才会显示新条目。

这里是我的define_index ...

define_index do 

    indexes(title) 
    indexes(entry) 

    has user_id 
    has created_at 
    has updated_at 

    set_property :delta => true 

end

这里是我的production.sphinx.conf ...

} 

index entry 
{ 
    type = distributed 
    local = entry_delta 
    local = entry_core 
} 

任何想法我可能是做错了？

我知道这是旧的，但你应该考虑更新你的狮身人面像版本和去RT模型，而不是主+三角洲计划。
