For RISC OS the best bet is usually duckduckgo.com/lite/ (or
...go.com/html/') but these have an inherent problem - a lack of URL
variables! You need a little jiggery pokery with a PHP script to enable a
DDG site search FORM on your site to be free of Javascript.

Imagine you want to search for 'wrap' in the torrens.org manual. 
The URL you need to generate is:


Try it.

To make a form construct that string without Javascript, you have to
capture 'wrap' in your own form, append or prepend the 'site:stro...' bit
in your own PHP script and then submit the full search from that script.

It's easier than it sounds.

The HTML form on the site could be:

<form method="post" id="search" action="handlesearch.php">
<input type="hidden" name="site" value="stronged.torrens.org">
<input type="text" name="query" maxlength="255" size="25"> 
<input type="submit" value="Search StrongED Manual" />

And the file handlesearch/php just needs to be this:
    $s = "site:" . $_POST['site'];
    $q = $_POST['query'];
    $action="http://duckduckgo.com/lite/?q="; . $s . "+" . $q;
    header("Location: $action");

(This is how the RISC OS search works over at www.timil.com/riscos
by prepending 'risc-os+' to the search term.)

You can test the search form created with the exact code above right
