AngularJS: Change hash and route without completely reloading controller

I have a controller, with a route like this:

#/articles/1234

I want to change the route without completely reloading the controller, so I can keep the position of other stuff in the controller constant (lists that scroll)

I can think of a few ways to do this, but they're all pretty ugly. Is there a best practice for doing something like this? I tried experimenting with reloadOnSearch: false, but it doesn't seem to change anything.
