Laravel5 - how to correctly write route for search query string?

I'm working on an app, where I should be performing search on a table containing users. However, I cannot figure out how to correctly compose the route in order to attach the view with the controller and back. My code is the following: The view:

<form action='' method='GET'> <input class='form-control' type="text" name="keyword" placeholder="Search for user..."> </form>

The route: Route::get('users?keyword={$keyword}', 'UsersController@search');

The search() in UsersController:

`public function search() { $keyword = Request::get('keyword');

        $users = User::where("username", "LIKE","%$keyword%")
                            ->orWhere("firstname", "LIKE", "%$keyword%")
                            ->orWhere("lastname", "LIKE", "%$keyword%")
                            ->orWhere("email", "LIKE", "%$keyword%")
                            ->orWhere("phone", "LIKE", "%$keyword%")-get();

        return view('search', compact('users'));

    }`

Can someone please tell what would be the correct syntax? Thanks in advance!
