Although this is not a direct answer to your question, here are some resources that may help you as you are learning about search and getting it implemented in your Rails app.

---------------UPDATE----------------

Elasticsearch has been growing in popularity due to some modern awesomeness that it has, such as instant indexing. It has a ruby gem named tire. Definitely worth a look.

Tire has been retired, and has been replaced by Elasticsearch-ruby

Answer 2

Elasticsearch with gem searchkick

Answer 3

For people coming here and looking for a solution in Rails 4, try the following example:

Posts Controller:

class PostsController < ApplicationController
  def index
    if params[:search]
      @posts = Post.search(params[:search]).order("created_at DESC")
    else
      @posts = Post.all.order('created_at DESC')
    end
  end
end

Post Model:

def self.search(search)
  # Title is for the above case, the OP incorrectly had 'name'
  where("title LIKE ?", "%#{search}%")
end

The index.html.erb remains the same apart from the search form:

<%= form_tag(posts_path, :method => "get", id: "search-form") do %>
  <%= text_field_tag :search, params[:search], placeholder: "Search Posts" %>
  <%= submit_tag "Search" %>
<% end %>

Note that the paths, controllers and columns you are using may be different.
