lucene.1278.5.7.2008.patch
lucene.1278.5.7.2008.patch - RangeFilter, FieldCacheImpl,
ExtendedFieldCacheImpl automatically use termenum loaddocs=true. A byte buffer
is used to load the docs, if the bytes read will exceed the buffer, a new
IndexInput is created and a DocIdSetIterator will read over that when
TermEnum.docs() is called. This makes the usual case of a small number of docs
(usually 1) to a term fast using a byte buffer. It also removes the issue if a
term has too many docs and the whole byte array is loaded into ram.
TermEnum.docs() returns DocIdSetIterator.
lucene.1278.5.7.2008.test.patch - TestSort stores documents with
Field.TermDocs.STORE
> Add optional storing of document numbers in term dictionary

> 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}
