I've seen it mentioned that -cw is for Cable & Wireless. Is that true and could that explain why I get newfangled results at home with a cable connection and the old index at work a mile away? Both are with local companies. The consistency is pretty obvious at the two locations although both occasionally give a result from the opposite index.
If I click on the smiley voting button for all -in results, will that help?;)
Naturally, I'm at home now and consistently getting the old index on cable. Oh well.
