Search url encoding looks like crap

I’m trying to search records with a date and the url looks like crap.
Here is a url:[(3i)2(1i)2007(2i)8(2i
from what I’ve read its URL encoding. How can I get rid of it and make
my url clean? Would I have to use a custom route? Thanks for any help.

Oh, here is my view:

<% form_tag attendances_path, :method => ‘get’ do %>

Search attendances by date: <%= date_select :search, params[:search], :use_short_month => true, :order => [:month, :day, :year] %> to <%= submit_tag 'Search', :name => nil %>

<% end %>
