Ning Li commented on LUCENE-1035: --------------------------------- > That seems like quite a few docs to retrieve--any particular reason why? I was guessing most applications won't want all 590K results, no? Lucene is used in so many different ways. No represent-all use case. > I echo Hoss' comment--proximity searching is important even if it isn't used > much directly by users. Hmm, I agree with you and Hoss, especially in applications where proximity is used to rank results of OR queries. > Optional Buffer Pool to Improve Search Performance > -------------------------------------------------- > > Key: LUCENE-1035 > URL: https://issues.apache.org/jira/browse/LUCENE-1035 > Project: Lucene - Java > Issue Type: Improvement > Components: Store > Reporter: Ning Li > Attachments: LUCENE-1035.patch > > > Index in RAMDirectory provides better performance over that in FSDirectory. > But many indexes cannot fit in memory or applications cannot afford to > spend that much memory on index. On the other hand, because of locality, > a reasonably sized buffer pool may provide good improvement over FSDirectory. > This issue aims at providing such an optional buffer pool layer. In cases > where it fits, i.e. a reasonable hit ratio can be achieved, it should provide > a good improvement over FSDirectory. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
