[ http://issues.apache.org/jira/browse/LUCENE-550?page=all ]
Karl Wettin updated LUCENE-550:
-------------------------------
Attachment: instanciated_20060527.tar
This update makes InstanciatedIndex compatible with Lucene, given that issue
580 and 581 is adopted.
It depends on generics and concurrent locks from J2SE 5.0.
Contains one update in Field:
public setFieldData(Object fieldData)
And one in Document:
public List<Field> getFields() {
return fields;
}
> 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,

> 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.
