Search Multiple Columns In Model Rails 3 - ruby-on-rails-3

Question

I now have a simple search form that will search one column in my model and return results as expected, however I would like to build upon this by being able to search upon 4 columns within the same model, using 4 text_field/Select_tags.
I have looked at Gems that provide this like solr for example but my thinking is that it seems a bit overkill for what i want to achieve, especially on such a small app
the app is simple, you can upload recipes, add recipes to favourites and search recipes.
So far it looks like this
Controller
def search
#countrysearch = Recipe.where(:country_of_origin => params[:search]).all
end
Search Form
<%= form_tag({:controller => 'search', :action => 'search'}, {:method => 'get'}) do |s| %>
<%= text_field_tag :search, params[:search] %>
<%= submit_tag "Search" %>
<% end %>
Output (View)
<% #countrysearch.each do |r| %>
<tr>
<td><%= r.dish_name %></td>
<td><%= r.country_of_origin %></td>
<td><%= r.difficulty %></td>
<td><%= r.preperation_time %></td>
<td><%= ingredient_names(r.ingredients) %></td>
<td><%= preperation_steps(r.preperations) %></td>
</tr>
I would like my search form to mirror my "Create New recipe Form" with select tags
<%= f.label :dish_name, "Dish Name" %>
<%= f.text_field :dish_name, :placeholder => "Enter Dish Name" %>
<%= f.label :country_of_origin, "Country Of Origin" %>
<%= f.select :country_of_origin, [['Wales'],['Scotland'],['England']], {:include_blank => 'Please Select'} %>
<%= f.label :difficulty, "Difficulty Level" %>
<%= f.select :difficulty, [['Beginner'],['Intermediate'],['Expert']], {:include_blank => 'Please Select'} %>
<%= f.select :preperation_time, [['15..30'],['30..60'],['60..120']], {:include_blank => 'Please Select'} %>
<% end %>
Just some pointers in the right direction would be appreciated. Thank you

You can do it using all the parameters you have passed to controller:
def search
#countrysearch = Recipe.where({:dish_name => params[:search][:dish_name], :country_of_origin => params[:search][:country_of_origin], :difficulty => params[:search][:difficulty], :preperation_time => params[:search][:preperation_time]}).all
end
This should work for you. There are other alternatives, but if you want a simple one, this may fit you.
Edit:
If you don't have other things in your search for, you can do something like this:
<%= form_tag({:controller => 'search', :action => 'search'}, {:method => 'get'}) do |s| %>
<%= text_field_tag :dish_name, params[:dish_name] %>
<%= select_tag "country_of_origin", options_from_collection_for_select(#recipes, "country_of_origin", "country_of_origin_name")
<%= select_tag "difficulty ", options_from_collection_for_select(#recipe, "difficulty ", "difficulty ")
<%= select_tag "preperation_time", options_from_collection_for_select(#recipe, "preperation_time", "preperation_time")
<%= submit_tag "Search" %>
<% end %>
Then in the controlelr just pass the parameters directly
def search
#countrysearch = Recipe.where(params).all
end
