If you install the SafeSearch policy from KB 000021435, Google searches for a specific website show the website in results, but with some elements (such as images or Google maps) on the web site missing. After refreshing the page, the browser shows everything correctly.
Turn off the instant search function of Google search, use the following rewrite (put this above the safe search policy):
<proxy> condition= BC_SafeSearch_Google_Domains
url.query.regex = "ion=0"
define action googlerewrite
rewrite(url, "(.*)", "$(1)?complete=0&ion=0")
The "ion=0" string forces google instant to be disabled and "complete=" disables autocomplete. For more information, see http://code.google.com/p/chromium/issues/detail?id=110598.
Alternatively, you can disable instant search in the user's Google account settings.
