SharePoint 2013 Search allows you to easily find the content that you are looking for unless you’re looking for pages with Friendly URLs in the list view.
When working with catalogs and cross-site publishing SharePoint 2013 automatically rewrites links between catalog items so that those links work wherever the catalog is published.
When working with Managed Navigation, menu items linked to pages with specific permissions set are automatically hidden from users without those permissions.
When working with Managed Navigation, menu items linked to pages that haven’t been published yet, are automatically hidden from anonymous visitors.
If you try to hide Navigation Terms pinned from a catalog in the navigation, URL rewriting for catalog items will break and you will see the physical URLs of those items instead.
