 ## Customizations
 
-- Ransack options can be customized defining a `ransack_options` method in the controller, example:
+- Ransack options can be changed defining a method `ransack_options` in the resource controller
+- The Ransack results by default use _distinct_, to change this behavior it is possible to define a `ransack_result_distinct` method
+- When a search term is not recognized a flash alert is shown (using a value from locales at `administrate_ransack.errors.invalid_search`), a custom behavior can be apply defining a method `invalid_search_callback`
