多关键字搜索

Question

I currently have a basic search that will allow me to type in a word and it will return back all records that are like that search. It is as followed:

application.html.erb

        <%= form_tag games_path, :method => 'get' do %>
            <%= hidden_field_tag :direction, params[:direction] %>
            <%= hidden_field_tag :sort, params[:sort] %>
            <%= text_field_tag :search, params[:search] %>
        <%= submit_tag t('.searchb'), :game_name => nil %>
        <% end %>

controller and Model

        @games = Game.search(params[:search])

  def self.search(search)
     search = search.to_s.strip.split
     search.inject(scoped) do |combined_scope, search|
     combined_scope.where(['game_name LIKE ? OR genre LIKE ? OR console LIKE ?', "%#{search}%", "%#{search}%", "%#{search}%"])
    end
  end   

What I now wish to do though is the ability to enter multiple words in to the search bar and have it return all related records to those words rather than any record that has them all.

eg If I type fighting, action

I want it to return all fighting games and all action games.

How would I go about implementing this? Model:

Answer 1

You should use a fulltext search engine like Sphinx for this! There is a gem called thinking-sphinx wich offers an interface between ruby and the Sphinx server! The only downside is that you need to update the database periodly. It doesnt support live updates.

Answer 2

You have to take the key words, loop them and create queries to achieve this. You can use inject to make it easy. This might help.
