After a recent upgrade to a newer ferret version and acts_as_ferret plugin, searching is not working any more.
I have changed find_by_contents to find_with_ferret, but it still doesnt
work. 
user.rb acts_as_ferret({:fields => ['username', 'lastname', 'town'})
search form.rhtml <% form_tag({ :action => "search" }, :method => "get") do %> <%= text_field_tag "q", params[:q] %> <%= submit_tag "Search" %> <% end %>
controller: def search if params[:q] @users = User.find_with_ferret(params[:q]) end end
Any help would be most welcome. Thank you.
