After pressing enter which dismisses the dialog, you're now back to your document with the current search criteria still defined. Press ⌥⌘F to apply that search criteria to the rest of the document.

As you state, ⌘F highlights the "Next" button so pressing enter does just that (aka, finds the next result). What I'm looking for is the behaviour that exists when you press ⌘F which changes the focused button to "find all" so that when you press enter it shows all the matches to your search phrase. Make sense?
