Or even better search on both fields (stemmed and unstemmed, I generally also have a ASCII-folded one) with SHOULD. An exact match would get higher score (because it hits both closes, stemmed and unstemmed field), while an only-stem match automatically gets a lower score (because only one Boolean clause matches).
