I need a .Net regular expression that matches anything OTHER than the exact full string match specified. So basically:

^Index$

... is the only exclusion I care about. Strings can start with, finish with or contain "Index", but not match exactly. My brain doesn't seem to be working today and I'm failing to work this one out.

EDIT

The answer MUST be via the pattern itself, as I am passing an argument to a third party library and do not have control over the process other than via the Regex pattern.
