Furthermore syntax like +(-A +B) and -(-A +B) appear to be legal to Luke, though I have no clue what this even means in simple English.
Let me try: +(-A +B) -> must match (-A +B) -> must contain B and must not contain A -(-A +B) -> must not match (-A +B) -> must not (match B and not contain A) As chris mentioned, they don't mean much outside the rest of the query... tack on "X Y " to both, and you get: SHOULD contain X, SHOULD contain Y, MUST contain B, MUST NOT contain A SHOULD contain X, SHOULD contain Y (effectively, MUST contain X or Y), MUST NOT (contain B without containing A) HTH, -Mike --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
