Um, "part of"? -- I don't think MySQL text search handles that...

It depends on your exact requirements, of course, but your examples
all look like a non-word character -- \W -- followed by your keyword
followed by another non-word character; that's a single replacement.

The only real problem I can see is with stemming, which -- if I recall
correctly, and it's been a while since I've done this -- is a bit of a weak
point with MySQL's text search, anyway. Grain of salt, etc.

I mean, even Lucene doesn't have a built-in stemmer, and that's just
nuts. But since I haven't volunteered to fix it, I can't complain, can I? :-)

In any case, I'd just try a \Wkeyword\W replacement and see how many
cases that hits.
