注:rails的版本是2.0以上.

1.在application.rb里添加分頁信息方法:

1 def page_for(result,options={})
2 
3       default_options = {:per_page => 10}   
4        options = default_options.merge options   
5        pages = WillPaginate::Collection.new(options[:page],options[:per_page],result.total_hits)   
6         return pages
7     
8     end

2.users_controller.rb里添加search方法:
3.view頁面:

按照網上傳統的方法安裝幾次都沒有成功.最后只有下載gem文件安裝
1.下載ferret-0.11.6-mswin32.gem文件
2.用gem 安裝:gem install ferret-0.11.6-mswin32 --local
3.gem install acts_as_ferret
4.從網上下載ferrect_ext.so文件,copy到 ferret-0.11.5-x86-mswin32\lib目錄（跟ferret.rb同一目錄）

如果直接下載源碼安裝運行ruby setup.rb.會出現"the c extensions could not be installed"的錯誤


手動安裝plugins

將下載的源文件放到vendor/plugins里面,進入該目錄,運行ruby install.rb

出現的問題:

 解決辦法就是把上面安裝完成ferret后的文件里找到ferrect_ext.so將這個文件放到lib里面.這個是200多K,而從網上下載的才30K.導致上面的問題.
