Although I spoke to a Quickbooks customer service rep for 2 hours today, we were still unable to figure out why I can't search for a customer by address. She showed me the QuickBooks Test Drive account and in that account I was able to search vie address, so there shouldn't be any reason why in my own business account I can't also search vie street address. 

This problem needs to be resolved ASAP! I've been reporting this issue for over a year now. 

Help please, software engineers...
