[jira] Resolved: (LUCENE-1278) Add optional storing of document
numbers in term dictionary
[ https://issues.apache.org/jira/browse/LUCENE-1278?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Michael McCandless resolved LUCENE-1278.
----------------------------------------
Resolution: Won't Fix
I think the pulsing codec (wraps any other codec, but inlines low-freq terms directly into the terms dict) solves this?

> Reporter: Jason Rutherglen
> Priority: Minor

> 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}
