Hi all, I want to use acts_as_ferret''s multi_search to search two model classes (Reviewable and Blog) at a time like @results = Reviewable.multi_search("jemen", [Blog]) and I''m always getting the error You have a nil object when you didn''t expect it! You might have expected an instance of Array. The error occurred while evaluating nil.map #{RAILS_ROOT}/vendor/plugins/acts_as_ferret/lib/class_methods.rb:131:in `id_multi_search'' #{RAILS_ROOT}/vendor/plugins/acts_as_ferret/lib/class_methods.rb:113:in `multi_search'' #{RAILS_ROOT}/app/controllers/search_controller.rb:53:in `search'' I have configured indexing like this: acts_as_ferret :fields => [:index_text, :index_locations], :single_index => true acts_as_ferret :fields => [:index_text, :index_locations], :single_index => true Maybe I''m doing something wrong?

Sorry, the above error is for the bleeding edge version (wrong cut & paste). Nevertheless for the stable version I get (in the same scenario): can''t convert String into Array RAILS_ROOT: C:/INSTAN~2.6-W/rails_apps/abb/config/..

In the single_index case, you tell find_by_contents what additional models to search with the :models option: @results = Reviewable.find_by_contents("jemen", :models => [Blog]) or @results = Reviewable.find_by_contents("jemen", :models => :all) this indeed looks a bit like an inconsistent API, however it''s this way because in the single_index case you have only one Ferret index (hence find_by_contents is used), while multi_search runs a combined search across multiple Ferret indexes. Maybe in a future version I''ll integrate the multi_search functionality into find_by_contents, too. Jens -- Jens Kr?mer webit!
