[jira] Updated: (LUCENE-550) InstanciatedIndex - faster but memory
consuming index
[ http://issues.apache.org/jira/browse/LUCENE-550?page=all ]
Karl Wettin updated LUCENE-550:
-------------------------------
Attachment: lucene2karl-061122.tar.gz
This is the current version of my local Lucene branch, including InstantiatedIndex. As I have not merged with the trunk for a while, it also features my locally patched version. It really is just a few small changes. Some classes are no longer final, plus I have introduced InterfaceIndexWriter and InterfaceIndexModifier.
/lucene2karl/lucene2-apache-karl-patched
/lucene2karl/lucene2-karl/test <--- all (search) test cases adapted to run with instantiated index
/lucene2karl/lucene2-karl/index
/lucene2karl/lucene2-karl/instantiated
/lucene2karl/lucene2-karl/searchfork <--- non important stuff
/lucene2karl/lucene2-karl/analysis <--- just some stuff
/lucene2karl/lucene2-karl/core <-- patches for the lucene trunk
/memoryindex <--- stuff for wolfgang
All tests pass, except remote, multi and parallell searchers.

> 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.
