• Show all items - a 'Preferred Items Only' option will appear in the 'Item Search' screen. Checking this box will override the default search preference and return only preferred items in the Search Results screen.
• Show preferred items only - Only catalogues and items marked as preferred will display in catalogue search results. It is not possible for the user to override this.
