> Add optional storing of document numbers in term dictionary.  String index field cache
and range filter creation will be faster.  
> Example read code:
> {noformat}
> TermEnum termEnum = indexReader.terms(TermEnum.LOAD_DOCS);
> do {
>   Term term = termEnum.term();
>   if (term == null || term.field() != field) break;
>   int[] docs = termEnum.docs();
> } while (termEnum.next());
> {noformat}
> Example write code:
> {noformat}
> Document document = new Document();
> document.add(new Field("tag", "dog", Field.Store.YES, Field.Index.UN_TOKENIZED, Field.Term.STORE_DOCS));
> indexWriter.addDocument(document);
> {noformat}
