Question

我有一个Rails 3.2.6应用，我正在使用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中。或者如果他们删除了一个帖子，它将不会显示，从他们删除它的那一刻开始。

我遵循了有关delta indexing的文档。

根据这个建议，我有一个每20分钟执行一次的cron作业并运行bundle exec rake ts:index RAILS_ENV=production ......

启用增量索引并不会消除定期运行完整重新索引的需要，否则增量索引本身将变得与核心索引一样大，这就消除了将其保持独立的优势。它还会减慢您对服务器的请求，从而更改模型记录。

只有在该作业运行后才会显示新条目。

这是我的define_index ...

define_index do

  indexes(title)
  indexes(entry)

  has user_id
  has created_at
  has updated_at

  set_property :delta => true

end

这是我的production.sphinx.conf ...

  sql_attr_uint = user_id
  sql_attr_timestamp = created_at
  sql_attr_timestamp = updated_at
  sql_query_info = SELECT * FROM `entries` WHERE `id` = (($id - 0) / 1)
}

index entry_delta : entry_core
{
  source = entry_delta_0
  path = /opt/deployed_rails_apps/my_app/releases/20120713022228/db/sphinx/production/entry_delta
}

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

任何想法我可能做错了什么？

我知道这已经过时了，但您应该考虑更新您的Sphinx版本并转而使用RT模型而不是主+ delta方案。
