So, for example:

You set filtering. This will filter also words that have "bad" in the text though they have nothing to do with that word, such as.

Then, you can set filtering  (  is for "word boundaries"). However, you may want to filter also  which isn't filtered in this case.

So it is up to you to be careful what you are setting for the filtering.

This all has nothing to do with the abuse filter itself, it is all related to regular expressions. This is something that is wastly described on the internet (I already gave you a link with some basics), so you shouldn't have problems to learn it.
