Hi Icdoo,
From Streets & Trips 2009 onwards the FIND UI in the Advanced toolbar serves as a single search text box for addresses and for business searches.
When you are connected to Internet and search for a business, e.g. 'Pizza, Bellevue, WA' then you get "Online results" from
Bing that also includes ratings and reviews.
And when you are not connected to the internet and search for businesses then you get the results from the local POI or "Offline results" (Find Nearby Place data) which does not have ratings and reviews.
You can also make Streets & Trips search only for Offline results when connected to the Internet by unchecking the 'Search using Live Search when online' checkbox under Tools menu - Options (Settings Tab)
