Attribute search status

Primary key
Primary keys distinguish an object from all other objects in the database. To update a primary key, you must delete the entire object and them create a new object with the updated information.
Lookup key
Attribute can be queried in the database to return the object.  Please note, however, that a lookup key does not uniquely identify an object.
Inverse key
Attribute can be used when performing an inverse query using the -i flag. For example, the query

-i mntner <MNTNER-NAME>

will return all objects with the specified maintainer in the mnt-by attribute.
