"foobar" you could use "\(foo\)\@!...bar", but that doesn't match a
bar at the start of a line. Use "\(foo\)\@<!bar".
+ Useful example: to find "foo" in a line that does not contain "bar": >
+ /^\%(.*bar\)\@!.*\zsfoo
+< This pattern first checks that there is not a single position in the
+ line where "bar" matches. If ".*bar" matches somewhere the \@! will
+ reject the pattern. When there is no match any "foo" will be found.
+ The "\zs" is to have the match start just before "foo".
