first use session variables it will manage the cookie for you

<?php
session_start();
?>

this as to be in the code before any headers are sent ie.: ( or header(); or anything like that)

<?php
$_SESSION['myquery']=$_SERVER['QUERY_STRING'];
?>

i would suggest you also check what's in $_SERVER['HTTP_REFERER'] you casn find what he type in google like this
