How to read the index in terms order

[Jean-Claude Dauphin]

Dear all,

I am pretty sure it's trivial and I apologize for raising this issue.

I wish to access the index in the order driven by:
   Term+"Field name"+Frequency or
   Frequency+Term+"Field Name".

I read the terms in the order driven by "Field name"+Term+°Frequency as
follow:

  Directory fsd = FSDirectory.open(indexLoc_,
NoLockFactory.getNoLockFactory());
 IndexReader reader = new TermIndexReader(IndexReader.open(fsd, true));

 TermEnum     terms  = reader.terms();
 while (terms.next) {
    Term term     = terms.term();
    int  termFreq = terms.docFreq();
    v.add(new DictionaryTerm(term, termFreq));
  }

   It works fine, but how to change the reading order?
   Can I use a custom SortComparatorSource class?

   Any advice or code example would be appreciated

   Best,

  JC
