Jason Rutherglen commented on LUCENE-1278:
------------------------------------------
Have a new patch that handles deleted docs but realized that returning
DocIdSetIterator is not needed. This implementation can integrate with
TermDocs transparently. The issue is then whether to keep the
Fieldable.isStoreTermDocs or make the implementation a default for untokenized
fields. For untokenized fields, this would mean not having to store the docs
in the segment.frq file.

> 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}
