I have an issue with word filters in 4chan X. If I want to filter a certain word, how do I stop the filter from targeting unrelated words that happen to contain that string of letters?

Example: Let's say I want to filter "low" but specifically the word "low", not just the sequence of the letters L, O and W. So I wouldn't want a post to be filtered that mentions pillows because it doesn't directly use the word "low" and should be fine.

Is it even possible to do what I'm asking for?
