Actually your first example finds 67 matches on my emacs.

Your second example is an unfair comparison, as my proposal was that 
at least two matching words should be required.  This can be illustrated
by (apropos "\\(find\\|file\\).*\\(find\\|file\\)") which finds 74 hits.

So I don't see the big difference...  The reason there are a few more
matches with the second pattern is that it also finds entries with
either word occurring twice. 

But I never claimed my sample implementation is perfect :-)
