Setup Google coop search engine, following their instructions
Create a new page template in Wordpress - I copied wordpress/wp-content/themes/default/page.php to ./googlesearchcoop.php, but you can just create a new file just as easily:
cd $your-wordpress-directory cd wp-content/themes/ cd $your-current-theme touch google_search_coop.php
<?php/* Template Name: Google Coop Search Setup*/?>?
<? php get_header(); ?>
<? php get_footer(); ?>
Then click Save Changes, and then copy and paste the code from the text areas, and paste them into your new Wordpress page template, between the header and footer snibbets.
This is the key step: add a new page using the Wordpress "Write Page" tab, save an empty page using your new page template (expand the Page Template tab on the right hand side, and you should see your new template).
<input type="hidden" name="page_id" value="16"/>
I'm not sure if that last step is required, but I did it and it works. :-)
Last but not least, the working example:
