## 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.
## 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](🔗).
