Hi Jens, I copied the demo folder into my rails apps and also created the ferret_production and ferret_test databases. when I start the server and type this in the browser: localhost:3000/content I get the following error: NameError in ContentController#new uninitialized constant Ferret::Search::BooleanClause RAILS_ROOT: ./script/../config/.. Application Trace | Framework Trace | Full Trace F:/InstantRails/ruby/lib/ruby/gems/1.8/gems/activesupport-1.4.2/lib/active_support/dependencies.rb:263:in `load_missing_constant'' F:/InstantRails/ruby/lib/ruby/gems/1.8/gems/activesupport-1.4.2/lib/active_support/dependencies.rb:452:in `const_missing'' #{RAILS_ROOT}/vendor/plugins/acts_as_ferret/lib/a Could you please tell me what''s going wrong?
