Resize the eSearch Widget Default Box Size (or other widgets)

Is there a way to resize the default size of the eSearch widget? I have a search that is 2 lines and it results in a little scrollbox appearing on the right side so the user can scroll, or they can manually stretch the box with the grip. Also, if it's possible to relocate the box a little bit for its default position on the screen, I'd like to nudge it a bit.

Any ideas if this is possible? I'm using compiled Flex.
