      @students+=@search.all

View
<% @students= @students.sort_by(&:last_name) %>
i am able to sort it but not in alphabetical order. Help me

Cheers,

What do you mean that you *are* able to sort it but not in
alphabetical order? Please explain what is happening and what you
expect to happen. Give a short example if necessary. Note that it
would be better to do the sort in the controller rather than the view
unless you have a good reason for doing it in the view.
