Experience
google_site_search.php
This singleton class allows for us to connect to a site search index at Google and query it for particular keywords. Because Google only allows for paginated responses in groups of 10, we handle amassing the listings so greater numbers of listing returns can be retrieved.
Example usage, including passing in a smarty tpl object and amazon elasticache obj which are provided via a mini-controller handling the request:
$gss = new google_site_search($this->sto, $this->_ec);
$gss->search_for('spicy asian buffalo wings');
die('', print_r($gss->search_listings, true));
