How can I read records from Lucene

Hi,


I would like to read the term and its frequency or score out of indices. How can I do it using Java?


Thanks!

IndexReader has assorted methods for reading terms and frequency
vectors.  See the javadocs for that class and TermDocs and TermEnum
and TermFreqVector.  Score is only relevant after a search.  See
TopDocs and ScoreDoc.

If you want more specific advice, ask a more specific question.  Or use Google.
