AppleInsider takes today a look at Safari 5.2

Safari has a history of delivering innovative new features while retaining one of the simplest user interfaces among major browsers available. In Mountain Lion, Safari removes the Google search field (and its SnapBack button) to leave one single location field.

From that single field, you can now just type the beginning of a website location, a search engine query, or reference a saved bookmark or recently visited page in your history. Safari continues to suggest alternatives as you type, but now it populates the results with potential searches recommended by Google (which remains the default search engine; Yahoo and Microsoft remain alternative options for search).
