我使用的是ts版本2.0.5,rails 3.0.9和mysql2 0.2.11

当尝试使用rake ts:index创建索引时,出现以下错误:

ERROR: source 'technical_core_0': unknown type 'mysql'; skipping.

我的development.sphinx.conf包含:

source technical_core_0
{
  type = mysql
  sql_host = localhost
  sql_user = root
  sql_pass = 
  sql_db = ps_development
  sql_sock = /tmp/mysql.sock
  sql_query_pre = SET NAMES utf8
  sql_query_pre = SET TIME_ZONE = '+0:00'
  sql_query = SELECT SQL_NO_CACHE `technicals`.`id` * CAST(1 AS SIGNED) + 0 AS `id` , `orders`.`name` AS `author`, `technicals`.`id` AS `sphinx_internal_id`, 0 AS `sphinx_deleted`, 488243725 AS `class_crc`, IFNULL(`orders`.`name`, '') AS `author_sort`, `technicals`.`order_id` AS `order_id`, UNIX_TIMESTAMP(`technicals`.`created_at`) AS `created_at`, …

任何人都可以用简单的语言解释像Sphinx这样的全文服务器是如何工作的？在纯SQL中,可以使用这样的SQL查询来搜索文本中的某些关键字:

select * from items where name like '%keyword%';

但是在各种Sphinx插件生成的配置文件中,我根本看不到任何类似的查询.它们包含如下所示的SQL语句,它们似乎将搜索划分为不同的ID组:

SELECT (items.id * 5 + 1) AS id, ... 
       WHERE items.id >= $start AND items.id <= $end 
       GROUP BY items.id
..
SELECT * FROM items WHERE items.id = (($id - 1) / 5)

它可以用简单的词语解释这些查询是如何工作的以及它们是如何生成的？

我在Heroku上运行Rails 3应用程序.我正在使用Thinking Sphinx搜索引擎进入我的应用程序.为了使它与Heroku一起工作,我flying-sphinx按照Heroku文档中的建议为我的gemfile 添加了一个gem.

这就是我在gemfile中的内容

gem 'thinking-sphinx', '2.0.11' 
gem 'flying-sphinx',   '0.7.0'

根据这里提到的步骤https://devcenter.heroku.com/articles/flying_sphinx,添加了fly-sphinx插件(Heroku插件:添加flying_sphinx:木制)后,当我运行heroku运行fly-sphinx配置时出现以下错误:
