"is this really possible?" Well, sure.. of course it is possible, just a lot more work because the divide between having logic on the client and no logic on the client is quite big thus you often end up needing to solve problems in two ways (and these differences can permeate various layers of the app) and then commit to maintaining both. "such as the user typing into a box in a real time search application" Well you could always just not support real-time search if JavaScript is not enabled. The argument that JavaScript should be optional for all sites sort of pre-assumes that the experience when running sans JavaScript will be different, but you'll be able to get the same things done. In this one specific situation the difference being that you won't get any search feedback until you actually submit the form, old-school web style.
