Robert Muir commented on LUCENE-2829: ------------------------------------- Bloom filters and negative caches are nice, but please open separate issues! I am starting to feel like its mandatory to refactor the entirety of lucene to make a single incremental improvement. So, I'd like to proceed with this issue as-is, to make TermWeight explicitly do less seeks. > improve termquery "pk lookup" performance > ----------------------------------------- > > Key: LUCENE-2829 > URL: https://issues.apache.org/jira/browse/LUCENE-2829 > Project: Lucene - Java > Issue Type: Improvement > Components: Search > Reporter: Robert Muir > Attachments: LUCENE-2829.patch > > > For things that are like primary keys and don't exist in some segments (worst > case is primary/unique key that only exists in 1) > we do wasted seeks. > While LUCENE-2694 tries to solve some of this issue with TermState, I'm > concerned we could every backport that to 3.1 for example. > This is a simpler solution here just to solve this one problem in > termquery... we could just revert it in trunk when we resolve LUCENE-2694, > but I don't think we should leave things as they are in 3.x -- 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: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
