NoMethodError: You have a nil object when you didn't expect

Hi,

  I have tried to use searchlogic in my application...
in def index,
@search = AccounDetail.search(params[:search])
@account_details = @search.all

In index.rhtml
<%form_for @search do |f|%>
  <p>
    <%=f.label :name_like,"Name"%>
    <%=f.text_field :name_like%>
    <%=submit_tag :Search,:name=>nil%>
  </p>
<%end%>

I didn't get any search result...
i tried it with ruby script/console.
when i call @search.all, i got "NoMethodError: You have a nil object
when you didn't expect"

example

search=AccountDetail.search(:name_like_any=>"xx")
search.all

give me a suggestion to solve this problem

da manu.this prob is related with routes.yor are suppose to put that method in routes.rb

I left the rails application then I tried in ruby script/console

search=BankingDetail.search(:name_like_all=>"man")
search.all

i got error when i call 'all' method

NoMethodError: You have a nil object when you didn't expect it!
You might have expected an instance of ActiveRecord::Base.
The error occurred while evaluating nil.[]
