I'm looking for a way to filter out files that has certain keyword in a particular field.

For example, I tried stuff like:  
%subtitle% HAS NOT "Original"  
%subtitle% IS NOT "Original Mix"

Nothing seems to be working.

There are no such operators as IS NOT or HAS NOT.  
If you want to invert a filter expression, use NOT, like this:  
`NOT %subtitle% HAS "Original"`

Aha! Excellent. I did found the "NOT" in the manual, but it wasn't clear it could be used like this. Thanks!
