Match string not containg a certain phrase

I need to find all instances of the word "confidential" in a message except when it is used in the phrase "confidential and proprietary" in which case it is ok and I dont need to pick it up through regex.

Thanks all in advance! -P

Using word boundaries \b is also an option here.

\bconfidential\b(?! and proprietary\b)

You can use negative lookaround (http://www.regular-expressions.info/lookaround.html)

This regex will match: (confidential) (?!and proprietary) if your engine support lookaround.
