I think that ;
(a)"type of search" is important, why dont you have radio buttons or check box..this means results can be pulled from one service or a host of services, or something like that..
(b) At each desgin iteration of the screen, one also needs to do click analysis from a UX view point. As a user I just want to type in my search term and hit enter. Two actions. But with other varations the users is now forced to move to multiple clicks or keystrokes to active any results.
(c) Once we have an SERP, we should have a link under each return results that also has a translate this button , just how we have the current note button
