Directory searches are expected to return results for name fields that are not included in the name format or specifically in the results. We don't want to exclude users because their name field that meets the criteria does not appear in their name when formatted for the directory.

This means the directory results is going to include Middle Names, when you search a directory by a user's name.

For example, if you search "Christopher" - this will bring up users with the First, Middle and/or Last Name of Christopher.
