So you type your "optometry" in Quick Search Box on your freshly updated Android 2.2 phone and you only see four results despite the fact that you have hundreds of contacts with "optometry" in the notes?
Well, 2.2 changes the things a bit. Your "general" Quick Search Box has an icon on the left. Click it and select Contact Search+. Then type "optometry" and you will be able to scroll through your hundreds of contacts.
Better yet! Long press on your phone's desktop and select Widgets and add search widget. When asked select Contact Search+. Voila, you now have dedicated Contact Search+ Quick Search Box!
