Tom, openfts will index anything you want as long as you change the parser to suit your needs (just in case you have some extra time :). Having said that, IIRC, the default installation only indexes dotted values with three values, i.e. X.X.X but not X.X, eventhough a decimal type is defined in the parser I do not remember off the top of my head why it is not indexed (probably it has something to do with the initialization but I'm not sure).
