[ http://issues.apache.org/jira/browse/LUCENE-558?page=comments#action_12376784 ]
Grant Ingersoll commented on LUCENE-558: ---------------------------------------- IndexReader.document(int n) is still in there. All prior APIs work and the introduction of Fieldable is a drop in replacement for Field and should not break any existing APIs. You are right, however, about the missing files. I assumed SVN diff would get them. I will add them. I think we could easily combine the two issues to get the best of both worlds. Also, I added a skipChars mechanism which I think improves the case of uncompressed chars. > 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]
