In the RoleTailored client, the Search feature finds only pages and reports that are accessible from the navigation pane, which includes the Home button, Activity buttons, and Departments. So if you want to make a page or report available from search, then add it to the Home button, an Activity button, or Departments.
For information about adding pages and reports to the Home Button and Activity buttons, see Home Button Overview and Creating Activity Buttons for the Navigation Pane in the MSDN library.
To add a page or report to Departments, you add it to the MenuSuite object that is used by the RoleTailored client. For more information, see How to: Create and Modify a MenuSuite Object in the MSDN Library.
