I needed to phone my mother at one point this weekend.

Pulled up the Nexus phone dialer for one of the first times (I don't actually use my phone as a phone all that much). Said my mother's (full) name, saw a brief flash of her details, and they were promptly replaced with a bunch of we results for her name (lawyers in the UK and the like). Of course that's what I was looking for when I explicitly opened the contacts app and searched for someone in my contact list by name... of course.

Same thing if I search for my own name, or just search for my Mom's first name, or basically search for anyone else with a common name. I can search for people with uncommon names and it just seems to work because it ignores the contacts and finds them anyway, but really, that's kinda silly.
