title: Do not include hidden field in query string when submitting form with GET
body: <pre><code>http://localhost:3000/users?utf8=%E2%9C%93&amp;search=aen
  </code></pre>
  
  <p>Here's my form in the view:</p>
  
  <pre><code>&lt;% form_tag users_path, :method =&gt; 'get', :html =&gt; { :class =&gt; 'ui-form' } do %&gt;
      &lt;div class="ui-input ui-input-search"&gt;
        &lt;%= text_field_tag :search %&gt;
      &lt;/div&gt;
    &lt;% end %&gt;
  </code></pre>
  
  <p>Which generates a hidden field that gets submitted:</p>
  
  <pre><code>&lt;div style="margin:0;padding:0;display:inline"&gt;&lt;input name="utf8" type="hidden" value="✓"&gt;&lt;/div&gt;
  </code></pre>
