Detecting Stopword Hits

I have a search program and I need to tell the user when words from their query are ommitted due to matching a mysql stopword. I want an elegant solution which as I see now would be a query that could be run directly after a match against query to return stopwords that were identified by mysql. Does such a query exist?

If not that, is there a way to query the current stopwords in use by mysql? I see that the stopwords can be overriden by specifying a text file containing whatever you want... does this mean the default stopwords are also stored in a text file somewhere that I could open and get the list that way? This would work I guess because I could do a show variables like 'ft_stopword_list' to see what the filename is, the trick is knowing where the file for 'built-in' is. I'm guessing built-in means this word list is actually compiled into the myisam engine though =) I realize I could just put the current set of default set of stopwords listed in the manual into a table but the problem there is if they change in a later version of mysql it will be incorrect... very hard to maintain this also on the software side.

Any help or insight would be great... thanks in advance.
