In the address book search please include all fields for the search.
I have lots of contacts for event personnel from across the country. I add what events they do to notes. But there is no way of searching notes to show all the contacts associated with. Yes I could create individual address books for each event but this would get very cluttered and end up with multiple duplicates that aren't required.
Similarly search doesn't work for phone numbers.
Just appears to do so for a few fields.
