Rails multiple form_tag paths/implement global search

I have a similar question to this but still can't figure it out.

I am creating a rails app linked to a Neo4j database and have a number of models I want to search across with one search form. I am using elastic search.

My current code for searching within one model (works fine):

#/app/views/symptoms/index.html
<%=form_tag symptoms_path, class: "form-inline", method: :get do %>
  <div class="form-group">
    <%= text_field_tag :query, params[:query], class: "form-control" %>    
    <%= submit_tag "Search", class: "btn btn-primary" %>
    <% if params[:query].present? %>    
    <%= link_to "clear" %>
    <% end %>
  </div>
  <% end %>

#/app/controllers/symptoms_controller.rb
def index
  if params[:query].present?
    @symptoms = Symptom.search(params[:query], show: params[:show])
  else
    @symptoms = Symptom.all
  end
end

Currently this will only search within the symptoms model. I want to to create a 'global search' field that will search within the symptoms_path, allergies_path, and drugs_path.

Potential 'Global Search' code:

#/app/views/global_search/index.html
<%=form_tag [symptoms_path, allergies_path, drugs_path], class: "form-inline", method: :get do %>
  <div class="form-group">
    <%= text_field_tag :query, params[:query], class: "form-control" %>    
    <%= submit_tag "Search", class: "btn btn-primary" %>
    <% if params[:query].present? %>    
    <%= link_to "clear" %>
    <% end %>
  </div>
  <% end %>

#/app/controllers/symptoms_controller.rb
def index
    if params[:query].present?
        @allergies = Allergy.search(params[:query], show: params[:show])
        @drugs = Drug.search(params[:query])
        @symptoms = Symptom.search(params[:query])
    else
        @allergies = Allergy.all
        @drugs = Drug.all
        @symptoms = Symptom.all
    end
end

Any ideas for how I could implement this? Thanks in advance!

I'd probably suggest that you create something like a "search_controller" (rails generate controller search should help you do that). In there you can have an index action (or whatever you want to call your action) and then you just set up a route to point a URL to it such as this:

# config/routes.rb
  # Link the URL to the search controller's `index` action
  post '/search/:query' => 'search#index'

# app/controllers/search_controller.rb

  def index
    if params[:query].present?
      @allergies = Allergy.search(params[:query], show: params[:show])
      @drugs = Drug.search(params[:query])
      @symptoms = Symptom.search(params[:query])
    else
      @allergies = Allergy.all
      @drugs = Drug.all
      @symptoms = Symptom.all
    end
  end

Sorry if I'm misunderstanding, I'm not sure how much you've worked with Rails before
