本软件可以帮助Rails项目快速实现搜索／过滤页面。具体使用，请参照软件主页里的说明。

1. Include gem into Gemfile

   gem 'rails-simple-search'

2. Code in model (app/model/search.rb):

   class Search < RailsSimpleSearch::Base  end

3. Code in controller:

   @search = Search.new(User, params[:search])  @search.order = 'email'  # optional  @users = @search.run

4. Code in views:

   <% form_for @search, url => "/xxxxxx" do |f| %>      <%=f.label :email %>    <%=f.text_field :email %>      <%=f.label :state%>    <%=f.select "address.state_id", [['AL', 1], ...] %>  <!-- address is an association of model User -->      <%=f.label :post%>    <%=f.text_field "posts.comments.author" %>           <!-- the associations could go even deeper, isn't it POWERFUL? -->      <%=f.submit %>  <% end %>    <% @users.each do |user| %>   <%= # show the attributes of user %>  <% end %>

5. Add route for the post to url “/xxxxxx” (config/route.rb)

   match "/xxxxxx" => "yyyyyyy#zzzzzz"
