As I can see predictive search works well with default google search engine.
As described here, I change search engine to NCR mode:
http://www.google.com/search?{google:RLZ}{google:acceptedSuggestion}{google:originalQueryForSuggestion}sourceid=chrome&ie={inputEncoding}&q=%s
But not predictive search stops works..
I thought, that phrase in search engine google:acceptedSuggestion
should be responsible for predictive list in omnibox.. but it isn't.
How to setup NCR with predictive search?
