Doing a NOT matches of a pattern?

Can you just do a FILTER A BY NOT (matches 'pattern');

Or NOT matches 'pattern';

I have a list of bad words I DO NOT want to match and I am unsure how to
do this with the few hundred words I have.

You can do this pretty easily with python or perl streaming if you can't figure out a way in Pig.

Can't say I have tried any python streaming or such.

Is there a pig version required for this? My understanding was that this
did NOT work ?

This will work with almost any version. If it doesn't work for you, please
let us know.
