If you can afford to store TermVectors (disk is cheap, right?) then it will give you back the terms post analysis and you won't have to split again, which you would have to do if you use the getValues() approach. You might also hook into the Collector (HitCollector) and build it as you go, assuming you don't need the score docs structure. -Grant --------------------------------------------------------------------- To unsubscribe, e-mail: java-user-unsubscr...@lucene.apache.org For additional commands, e-mail: java-user-h...@lucene.apache.org
