Why add wildcard searches to the MAC, rather than some sort of
keywords attached some other way. Simple. Obvious: flexibility.
The *USER** can attach whatever meaning he wishes to a filename - 
with zero additional work, as a file has to have a name. And he
could
use that info any way he wishes. That is the real beauty of UNIX,
and other real OS shells. Flexibility - do what you wish. The
user is not limited to what the system designer wants him to do.
The MAC has a reasonably good, in fact very good, user interface
inside programs. But the top-level shell, the "finder", is
excruciatingly bad due to its limitations. Apparently even APPLE
recognizes this, as their development environments provide
more functionality. 

So, the bottom line is - provide an info section as part of 
files directory entries - but allow using any part of it - 
including the name, with the usual wildcards (or regular expressions)
to do searches, copies, deletes, etc.
