Writing regexps for matching "not something" is generally quite
difficult, especially if "something" is more than a single
character. Instead, I suggest you look to try and keep all
lines containing the letters "FK". Thankfully such a function
already exists. So you can do:
M-x keep-lines RET FK RET
and not have to worry about nasty regexps :)
