[ http://issues.apache.org/jira/browse/LUCENE-550?page=comments#action_12378776 ]
Karl Wettin commented on LUCENE-550: ------------------------------------ Oups InstanciatedIndex: Corpus creation took 14011 ms. Term queries took 33608 ms. RAMDirectory: Corpus creation took 9144 ms. Term queries took 1123565 ms. That it 35x the speed. Something might be wrong. But my initial tests tells me that it is right. Will look in to this tomorrow. Need to sleep now. > InstanciatedIndex - faster but memory consuming index > ----------------------------------------------------- > > Key: LUCENE-550 > URL: http://issues.apache.org/jira/browse/LUCENE-550 > Project: Lucene - Java > Type: New Feature > Components: Store > Versions: 1.9 > Reporter: Karl Wettin > Attachments: Document.java, InstanciatedIndex.java, Term.java, > class_diagram.png, class_diagram.png, src.tar.gz, src_20060509.tar.gz > > After fixing the bugs, it's now 4.5 -> 5 times the speed. This is true for > both at index and query time. Sorry if I got your hopes up too much. There > are still things to be done though. Might not have time to do anything with > this until next month, so here is the code if anyone wants a peek. > Not good enough for Jira yet, but if someone wants to fool around with it, > here it is. The implementation passes a TermEnum -> TermDocs -> Fields -> > TermVector comparation against the same data in a Directory. > When it comes to features, offsets don't exists and positions are stored ugly > and has bugs. > You might notice that norms are float[] and not byte[]. That is me who > refactored it to see if it would do any good. Bit shifting don't take many > ticks, so I might just revert that. > I belive the code is quite self explaining. > InstanciatedIndex ii = .. > ii.new InstanciatedIndexReader(); > ii.addDocument(s).. replace IndexWriter for now. -- 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]
