[turba] Turba with a less than complete table

[Mark Hennessy]

 I have a situation where I have turba looking at a table used 
 by another application as well for address book management.
 As such, there is no guarantee that there will be an e-mail 
 address filled in for any particular record in the database.
 
 Is it possible to have turba simply not return any record 
 that doesn't contain an e-mail address when a search or 
 browse is done?  I would think if so that this could extend 
 to other fields as well.
