Java -Lucene, .Net -Lucene: Score Compare
Hi,
I am trying to understand how is score calculation working.
I created some test , used:
1. Multifield Analyzer : PerFieldAnalyzerWrapper
2. Multifield Parser : MultiFieldQueryParser
Score calculated for Java and .net lucene is different. For Java - Lucene is mach less then for .net Lucene. Used the same index and the same query.
I used Java - Lucene - Version: Version.LUCENE_29; for .Net Lucene - Lucene.Net-2.0-004-11Mar07.
Is it different calculation ?
And another question: where and how I can grab latest version .net Lucene source code( Version 2.9 for example) as zip file for rebuild and test it on my computer.
Thanks,
Igor Ch.

Thanks,Anders
I did it but it's not convenient...
For searching I am using the same Analyzer for corresponded field.

No, you need to store the indexing information elsewhere

Hi All,
I am using Multifield Analyzer : PerFieldAnalyzerWrapper for creating Index.
Question: is it possible to get information what kind of Analyzer(KeywordAnalyzer(), StandardAnalyzer() ...) I used for particular field from created Index ?
Thanks

You can get the v2.9.2 from here
https://svn.apache.org/repos/asf/lucene/lucene.net/tags/Lucene.Net_2_9_2/
using a svn client(such as tortoise svn).
Please reask if you see any difference between java & .NET (using the same
versions)
