## Access right filtering of search results

When integrating Optimizely Search & Navigation with Optimizely Content Management System (CMS), the search engine does not filter documents (such as pages or files) according to access rights. However, the return values from the `IContent` extension methods `RolesWithReadAccess` and `UsersWithReadAccess` are indexed. You can use these methods to ensure that only users with access rights to the supplied roles/users see the content.

**Example:**



## Control access to UI features

Members assigned to the roles WebAdmins, Administrators, SearchAdmins, and SearchEditors can access the Search & Navigation user interface. Only WebAdmins, Administrators, and SearchAdmins can clear indexes. See [Shell module](🔗).
