New UI search

My biggest problem with the new UI (and in general it's OK) is the lack of a search function for contacts. In the old UI I could type "12345" in the search box and get any contacts whose phone number (or address or whatever) matched, In the new UI the search box seems non-functional. It displays a "what to search" drop-down then does nothing when "contacts" is selected. If I can't search... well... not very useful.
