i used to be able to search for a contact by using a part of his
telephone or mobile phone number thru advanced search on outlook 2003.

i've upgraded to outlook2007 and vista and i can no longer do it. it
returns a "No Matches Found" error.

I've checked the index and I am indexing the correct pst file and it
shows that indexing has been complete (0 records left to index)

pls help
