Can't find some documentation

Hi. When I select ActionController or ActionController::Base in my source code and hit Ctrl+Q to get its documentation, I get this instead (also see attached screenshot)

module ActionController in action_controller\metal\rack_delegation.rb  Partial declarations in: action_controller\metal\exceptions.rb,  action_controller\metal\responder.rb,  action_controller\metal\force_ssl.rb,  action_controller\caching\fragments.rb,  action_controller\metal\rescue.rb,  action_controller\metal\session_management.rb,  action_controller\metal\implicit_render.rb,  action_controller\metal.rb,  action_controller\test_case.rb,  action_controller\log_subscriber.rb,  action_controller.rb,  action_controller\metal\http_authentication.rb,  action_controller\metal\renderers.rb,  action_controller\metal\params_wrapper.rb,  action_controller\metal\request_forgery_protection.rb,  action_controller\middleware.rb,  action_controller\metal\mime_responds.rb,  action_controller\metal\data_streaming.rb,  action_controller\caching\pages.rb,  action_controller\metal\redirecting.rb,  action_controller\railtie.rb,  action_controller\record_identifier.rb,  action_controller\metal\url_for.rb,  action_controller\base.rb,  sass\plugin\rails.rb,  action_controller\metal\testing.rb,  action_controller\metal\hide_actions.rb,  action_controller\railties\paths.rb,  action_controller\metal\flash.rb,  action_controller\metal\compatibility.rb,  action_controller\metal\helpers.rb,  action_controller\metal\rendering.rb,  action_controller\metal\instrumentation.rb,  action_controller\caching\actions.rb,  action_controller\metal\cookies.rb,  action_controller\metal\streaming.rb,  action_controller\metal\conditional_get.rb,  action_controller\caching.rb,  action_controller\caching\sweeping.rb,  action_controller\metal\head.rb  
No documentation found.


Can I do something to fix it? May be I need to configure a link to the documentation somewhere?
