Paginate Multiple Models in Kaminari

I'm creating a search page that will do an application wide search on users, posts, and comments. I currently have:

# POST /search
def index
  query = params[:query]
  @users = User.search(query).page(params[:page])
  @posts = Post.search(query).page(params[:page])
  @comments = Comment.search(query).page(params[:page])

  respond_to do |format|
    format.html
  end
end

However I'm really trying to get something where all the results are mixed together then paginated. What are some of the strategies for doing paginated search like this? Thanks!
