This feels like a bit of a regression. I used to be able to just use the automatic search, but it seems to be breaking for more and more sites recently. Even sites it used to pick up automatically, like tpb, now need to be manually specified.
And there's still no damned excuse for them not being able to search maps.google.com from the omnibox.
You are coming off as incredibly pretentious. I was unaware that by typing in the search field and expecting relevant results I wasn't using Google correctly.
