Restrict access for author to only view their own documents

I have created a database with multiple users who can all create documents. How do I restrict access so the author’s of the documents can only view their own documents. Also set-up a manager who can view all documents. This database has been created using Notes 6.5.

Subject: Readers field …

Create a Readers field with a role that is given to the manager, or a group that the manager is in. (Doing this, rather than using the managers ID directly makes it trivial to change managers in the future.)

When a document has both Authors and Readers field, the Authors field also acts like a Readers field.

So each document will be seen by the Manager and the Author, and no one else.
