How do I get to *all* of the groups of an re search?

[Kyler Laird]

	http://www.python.org/doc/current/lib/re-syntax.html
	(...)
	    Matches whatever regular expression is inside the
	    parentheses, and indicates the start and end of a 
	    group; the contents of a group can be retrieved
	    after a match has been performed, [...]

Sounds good, so I tried it.

	import re

	text = 'foo foo1 foo2 bar bar1 bar2 bar3'

	test_re = re.compile('([a-z]+)( \\1[0-9]+)+')

	print test_re.findall(text)

I expected the matches to be something like
	[('foo', [' foo1', ' foo2']), ('bar', [' bar1', ' bar2', ' bar3'])]
but it's just this.
	[('foo', ' foo2'), ('bar', ' bar3')]

How do I get to the other groups that were matched?  (Is this
an FAQ?  I don't know where to start looking.)

Thank you.
