It's not an "error" - it's a "notice". If you read the PHP manual on error
handling, you'll discover that they're quite different things.

Try replacing that with:
if (isset($_GET['search'])) $search = $_GET['search'];
else $search = NULL;
Or even with the more compact ternary-operator form:
$search = isset($_GET['search']) ? $_GET['search'] : NULL ;
That should do it for now. And, while you're on it, read the PHP manual on
setting/unsetting variables - keep in mind that an unset (non-existent)
variable is very different from a NULL variable.
