Subject Re: Get the terms and frequency vector of an indexed but unstored field
Date Fri, 03 Aug 2007 11:36:48 GMT

you can use IndexReader.getTermFreqVectors(int n) to get all terms and their
frequencies. Make sure when you create an index, you choose option to store
it by specifying Field.TermVector option.
