On Windows XP I used Google Desktop Search which provided full text searches on files and emails with a preview of results, like a Google search. It indexed files when needed.
I'm looking for something like this on OS X Snow Leopard. Spotlight and Finder search don't produce a preview. Google desktop isn't the same thing on the Mac.
What can I use?

It's not quite the same thing, but you can use the Finder's search window (Option-Cmd-Space) and use Quick Look as your preview. When you have a Quick Look preview open, you can use the Up and Down arrow keys to scroll through the results without having to close and reopen the preview.
