Right, you'd have to work directly w/ the FSTEnum (ie, code changes). The FSTEnum "feels" like a TreeMap, so, you can eg seekFloor to eg 0xffffffff, get the term, seek the TermsEnum there, then .next() until you hit the end. Maybe we need a seekFloor in the TermsEnum? (What we have now is really seekCeil). But, what's the larger use case here..?
