Ruby on rails 像雪貂一样根本不搜索

我正在尝试让acts_as_ferret在我的rails应用程序中工作。我已经安装了

ferret

gem。安装了充当雪貂的

插件

这就是我的模型现在的样子

class User < ActiveRecord::Base
  acts_as_ferret :fields => {
    :first_name => {},
    :last_name => {}
  }

我甚至试着重建索引。不起作用。雪貂日志显示一切进展顺利

这是日志的快照

我在控制台的开发模式下测试这个。我是否错过了一个步骤，或者我是否需要运行一些索引过程（如ThinkingSphinx）？我做错了什么？
尝试查询

User.find_with_ferret 'first_name:Chirantan'

听起来您并不是在搜索所有字段。如果要指定字段，则需要使用默认字段选项。
谢谢。但由于我有几个小时没有得到回应，我改用斯芬克斯，效果非常好。不过我会试试你的建议。
