Filtering sent items

I'm having a problem filtering the sent items folder by
"urn:schemas:httpmail:to" LIKE '%emailaddress%' ... the search always
returns nothing.  Same is true for "urn:schemas:mailheader:to" LIKE
'%emailaddress%'.  I would use the displayto property but it is specific to
how an individual chooses to display a mail address unlike the email
address.

Any help in obtaining a filter to provide a list of emails sent to an
individual by email address would be appreciated.

Thanks
