Undefined method `each' for nil:NilClass with Ferret search

Hi All:
For certain key terms I always get this error; I had to rebuild the
indexes then it works for a while then again it is gone.

here is the message
ActionView::TemplateError (undefined method each' for nil:NilClass) on line #4 /usr/local/lib/ruby/gems/1.8/gems/actionpack-1.12.5/lib/action_view/base.rb:316:incompile_and_render_template’

I can’t see anything Ferret specific in your error message. This looks
like a Rails problem. You might be better off asking on the Rails
mailing list.
