[ http://issues.apache.org/jira/browse/LUCENE-558?page=comments#action_12376723 ]
Grant Ingersoll commented on LUCENE-558: ---------------------------------------- This is pretty much what I started out with when I first started working on Lazy/Selective Field loading and I think it is a little bit simpler than 545 but is easily handled by the code in 545. Discussions on Lazy/Selective field loading indicated that people wanted more control over the process. We could, of course, merge the two, and have this patch hide the details of creating the FieldSelector. Just a thought... > 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]
