ruby on rails search form

ruby on rails search form

I'm new to RoR and I've managed to make a basic search form but keep
getting errors when trying to expand the search tags (name).. I have a
model with various data (location, website, email, telephone) and was
wondering how I can add these to my current search code.
/models/ciir.rb
def self.search(search)
if search
find(:all, :conditions => ['name LIKE ?', "%#{search}%"])
else
find(:all)
end
end
static_pages_controller.rb
def home
@ciirs = Ciir.search(params[:search])
end
/home.html.erb
<%= form_tag ciirs_path, :method => 'get' do %>
<p>
<%= text_field_tag :search, params[:search] %>
<%= submit_tag " Search Database Records ", :name => nil %>
</p>
<% end %>
