Rails routes and querystring

I am having troubles trying to define the correct route for a query coming from ember. The request appears like this:

GET "/users?id=1011

No matter what I try I always have the request forwarded to the index action, while it is intended for the show action. I have tried many things, like

get "/users?id=", to: redirect('/users')

but nothing seems to work. Can anyone explain to me what can I do and most important the reason behind it? Thank you very much for your time!
