This is a regular expression that matches all words except 'foo'

\v<(foo>)@!\k+>

\v Very magic
< Start-of-word
(Foo>) The atom 'Foo' followed by end-of-word
@! Match (with zero length) when the previous atom doesn't match.
\k+ Match one or more Keywords
> Match end-of-word.

The non-magic version is:

\<\(foo\>\)\@!\k\+\>

The use of \@! can be very tricky. According to the Vim help files, it is often easier to use \@<! instead. For example, to find all 'bar' strings unless they are part of 'foobar', use the following (non-magic):

\(foo\)\@<!bar
