Absolute brainlet here, can someone please help me set up some filters for certain words and phrases on 4chanX? I tried a fuckload of methods but literally nothing works correctly.

For example, I currently got /\banal\b/ to filter 'anal', but I'm not even sure it works. Then there's the issue of if 'anal' is part of a different word which is unrelated, say 'analysis', 'analysis' gets filtered too. I don't fucking get it.
