Are you sure of that? After all, we don't have all the same interpretation for every word in the dictionary. Ask a hundred person in the street - well perhaps not these days - the meaning of the word "meaning", how many different explanations will you get? And will you be able to reduce them all to the same "fundamental" meaning?
Why is it hard? Honestly. Add a "t" to "no" and you get a basic Boolean query.
Boolean queries aren't statistically analyzed; they're parsed and algebraically evaluate. So your point seems to support the opposite thing you're supporting.
It's easy to say, isn't it? Unfortunately, sticking the word "just" in there doesn't affect the difficulty. I do it all the time, too.
