Yes, I found what I need is the term vector which is stored in the indexing time. I am appreciate you guide me to "Lucene in action", but I think the interface it offered is version 1.4. So I need to get the syntax for lucene2.0 for making the term vector add to the document when the indexing time. By the way, the sort function is lower-level and faster than i thought, it is nick work now(I've implemented ScoreDocComparator and comparator for my own!). Thanks a lot! And Best regards! :)
