Filter Function for Contacts.app

Question

Apple Contacts.app needs to be able to filter contacts with more flexible criteria.
I have maybe hundreds of useless contacts synced from Gmail. Neither Apple Contacts nor Google Contacts offers an ability to filter contacts with following criteria:
- have phone number but no email
- have email but no phone number
- have name but neither phone number nor email
- don't have name but both name and phone number
These filters seems impossible to achieve through the existing keyword search. (Maybe with "@" ?) and these would help organize my contacts dramatically more efficiently. For example:
- I would delete all contacts without either an email nor a phone number
- I would categorize all contacts without phone numbers into a group
- I would name all contacts with both name and phone number
Therefore, this improvement would be very useful.

The same sysops cover all the BM forums, therefore it doesn't matter.

Is the exception you made STATEFUL? If it's not stateful the return
packets will be dropped.
