Search form

Hello,

I am creating a help guide for users. All pages created will be under http://mydomain.com/help/

how can I limit search just to pages under “help” page?

here is the code used:

<div class=”centered”>
<form role=”search” method=”get” id=”searchform” class=”custom” action=”http://mydomain.com/”&gt;
<div class=”row collapse”>
<div class=”nine columns”>
<input type=”text” value=”” name=”s” id=”s”>
</div>
<div class=”three columns”>
<input type=”submit” class=”button radius small secondary expand postfix” id=”searchsubmit” value=”Cerca”>
</div>
</div>
</form>
</div>

I tried to put

<form role=”search” method=”get” id=”searchform” class=”custom” action=”http://mydomain.com/help/”&gt;

but nothing changes.

Thanks
