A quick test shows that Google, Yahoo, Lycos uses AND
while Altavista, Excite, AskJeeves uses OR.
That's 50/50...
For WEB search engines, I think AND does make sense -- since there
are SOOOO many pages to match. But for a limited universe like
emacs -- which doesn't always use the most obvious terms --
using AND doesn't make a lot of sense to me.

I think it is adequate in practice.

I don't see the relevance, sorry. But of course, we could ignore
commas in case people use them...

We could put a "button bar" at the top of the apropos output with
the following buttons:
[Match all words] [anchored match] [search documentation]
