[ http://issues.apache.org/jira/browse/LUCENE-558?page=comments#action_12376828 ]
Chuck Williams commented on LUCENE-558: --------------------------------------- You're right about IndexReader.document(int), although it appears you removed (package api) FieldsReader.doc(int). I've been reading the patch file (and now the new files) rather than applying the patch since it affects some of the same files as another patch of mine (LUCENE-362). Re. skipChars() do you have a newer version that is not attached? The version in your patch file takes, I believe, precisely the same number of instructions as mine. It's hard to see how to do it better without changing the index representation (to store byte count instead of char count for strings, which would require an extra seek to write a string). 545 is a good improvement. I was initiually put off by the scope of it. We don't need this issue (558). Is there interest in committing 545? > Selective field loading > ----------------------- > > Key: LUCENE-558 > URL: http://issues.apache.org/jira/browse/LUCENE-558 > Project: Lucene - Java > Type: New Feature > Components: Index > Versions: 2.0 > Environment: All > Reporter: Chuck Williams > Attachments: LuceneTrunk.patch > > Provides a new api, IndexReader.document(int doc, String[] fields). A > document containing only the specified fields is created. The other fields > of the document are not loaded, although unfortunately uncompressed strings > still have to be scanned because the length information in the index is for > UTF-8 encoded chars and not bytes. This is useful for applications that need > quick access to a small subset of the fields. It can be used in conjunction > with or for some uses instead of ParallelReader. > This is a much smaller change for a simpler use case than Lucene-545. No > existing API's are affected. > All the tests pass and new tests are added to verify the feature. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://issues.apache.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
