I found at least one link talking about the Chrome address bar auto site search. It looks like it has been around for a year or so and there might even be a way to get Google to automatically add this feature for a given website. I must research this in the future, but as of right now, it is a little off the beaten track of most users to take any priority level.
As a side note, I tested this feature on an iPhone running mobile Chrome and was disappointed to find out it isn't supported (yet?). Might try android later.
