This looks promising:
http://www.mckinneystation.com/2007/08/20/pagination-with-acts_as_taggable_on_steroids-acts_as_ferret-and-will_paginate/
You basically need to wrap the results from find_with_ferret in a
WillPaginate collection so that the will_paginate helper knows what to
do with it. This is ordinarily accomplished with the "paginate" method
when using ordinary finds, which find_with_ferret is not,
unfortunately.
By the way, Sphinx is generally considered better than Ferret for
search, and automatically returns will_paginate collections...
If notes is a rest resource, you might want to try note_path(note)
instead of notes_path.
