Checkbox search results

Hello,

I'm very new to rails and am trying to make a basic website where the
user select from a list of colors and gets results for things with those
colors from the database.

<%= form_tag("/fbcs", :method => "get") do %>

  <%= check_box_tag(:qgreen) %>
  <%= label_tag(:qgreen, "Green") %>

  <%= check_box_tag(:qred) %>
  <%= label_tag(:red, "Red") %>

  <%= check_box_tag(:qblack) %>
  <%= label_tag(:black, "Black") %>

  <%= check_box_tag(:qorange) %>
  <%= label_tag(:orange, "Orange") %>

  <%= check_box_tag(:qwhite) %>
  <%= label_tag(:white, "White") %>

  <%= check_box_tag(:qyellow) %>
  <%= label_tag(:yellow, "Yellow") %>

  <%= check_box_tag(:qblue) %>
  <%= label_tag(:blue, "Blue") %>

   <%= submit_tag("Search") %>
<% end %>

is my form.

My database has boolean fields for these.

I have been able to get results with direct names using

  @query = Fbc.where(:name => params[:qname])

but do not know how to successfully query my database with the form for
checkbox fields.

Any help or guidance is appreciated,
Thanks.
