The Quick Navigation search function in Conf 2.10.xx is something I want to include in the header of my custom theme (Builder 3.3.2-conf2.10). How can this be done?

I've placed html used in the confluence theme search into my theme header content:

{table:width=100%|cellpadding=0|cellspacing=0|border=0}
  {table-row}
    {table-cell:width=50%}{builder-breadcrumbs}{table-cell}
    {table-cell:align=right}
{html}
	<form id="quick-search" method="get" action="/dosearchsite.action">
		<fieldset>
			<legend>Quick Search</legend>
			<input id="quick-search-query" type="text" accessKey="q" autocomplete="off" name="queryString" size="25"/>
			<input id="quick-search-submit" type="submit" value="Search"/>
		</fieldset>
		<fieldset class="hidden parameters">
			<input type="hidden" id="quickSearchPlaceholder" value="Quick Search <ctrl>-q">
			<input type="hidden" id="quickNavEnabled" value="true">
		</fieldset>
	</form>
{html}

{table-cell}
  {table-row}
{table}

To no avail. I get the same search behavior as if I used a search-box macro.

Anyone have any ideas?

Is there a way to get the Quick Navigation search functionality in a custom theme?
