[ 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.
Jira admins: you are more than welcome to remove all old attachments, except
images.

> 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.
