Subject [jira] Commented: (LUCENE-1278) Add optional storing of document numbers in term dictionary
Date Wed, 21 May 2008 19:57:55 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-1278?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12598770#action_12598770
] 

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}
