我正在尝试在我的 RoR 网站上使用一个简单的搜索表单。我有以下代码：

（在 note_controller.rb 中）

  def search
    @results = Note.find_with_ferret(params[:term]).sort_by(&:ferret_rank)

    respond_to do |format|
      format.html
      format.xml { render :xml => @nootes }
    end
  end

（在 note.rb 中）

class Note < ActiveRecord::Base
  acts_as_ferret :fields => [ :title, :body ]
end

（在 index.html.erb 中）

<%= form_tag :action => 'search'%>
<%= text_field 'term', nil  %>
  <%= submit_tag 'Search' %>
</form>

（在 search.html.erb 中）

<h1><%= pluralize(@results.size, 'result') %></h1>

<ul>
<% for result in @results %>
  <li><%= result.ferret_score %>: <%= link_to result.tile, result %></li>
<% end %>
</ul>

正如您希望从上面看到的那样，我有一个模型，我已经告诉acts_as_ferret。然后，我的控制器中有一个搜索操作，它尝试呈现到 search.html.erb 视图。我在索引视图中有一个用于搜索的表单。但是，当我运行它时，我收到以下错误：

无法将数组添加到 BooleanQuery

我想我的表格做错了，所以雪貂以某种方式获取了错误的数据。我所做的 form_tag 事情是正确的吗？任何帮助将非常感激。

更新：

以下是我似乎可以从日志中提取的唯一一点。我正在使用 Heroku，它似乎并没有给出标准的日志文件。希望这会有所帮助。

我不记得曾经见过那个雪貂错误。有两个基本诊断：进入脚本/控制台，然后执行

Notes.find_with_ferret("一些应该在索引中的词")

然后看看当你删除索引的目录（/appname/index/development）时会发生什么，做另一个find_with_ferret来强制重新索引？

背景信息：表中的“标题”和“正文”列，或以实例方法计算，或来自例如 has_many 的子项？如果是表中的字段，迁移中声明的“title”和“body”是什么列类型，mySQL 的列类型是什么？

包括您的操作系统、ruby、rails、ferret 和您正在使用的 a_a_f 的版本通常也很有帮助。

我已经删除了索引目录，它似乎已经重新生成了自己，但现在我在控制台上的搜索没有给出任何结果。在我删除索引目录之前，我在控制台上得到了结果，但在我的应用程序的表单中使用时却没有。

Title 和 Body 都是我的 MySQL 表中的列。它们是分别使用 Rails 迁移作为类型字符串和文本创建的。

我在 Heroku 上运行 - 所以我不完全确定是什么操作系统（可能是 linux）或版本，尽管我知道它至少是 rails 2.1。我似乎也找不到 AAF 的版本号 - 但我想它是相对较新的。

抱歉，我无法提供更多帮助——我所说的有用吗？
