How to force nosslsearch.google.com instead google.com?

nrw

I need to avoid google ssl search, because this traffic impossible to filter by dansguardian (phrase filter).
Google recommended following (http://support.google.com/websearch/bin/answer.py?hl=en&answer=186669):

To utilize the no SSL option for your network, configure the DNS entry for www.google.com to be a CNAME for nosslsearch.google.com

So,
1. I added following lines into DNS forwarder "advanced" field:

cname=www.google.com.,nosslsearch.google.com.
cname=google.com.,nosslsearch.google.com.

2. Restart pfsense and ipconfig /flushdns on windows client host.

But it doesn't work >:( Google search still use ssl.
Where I made mistake?

Thanks
