What is the current production version?
I am a little confused about the current version of Lucene.Net that can used for production. In SVN I can see a tag for version 2.9.1 but the "stable" version on http://lucene.apache.org/lucene.net/ links to version 2.0.0 from 2 years ago.
Does anybody know what the current version is?
Thanks
Hans

Floyd,
In my performance testing I observed slightly faster performance when
sorting on a field value as opposed to the score as the score is not
calculated for the document in that case. Nothing significant, but
measureable.
Does that help?
Michael

Hi Michael,
Thanks for you information, but I'm not fully understand what you said.
Could you please explain this much more simpler. Sorry that English is
not
my native language.
Thanks in advanced

It's just that score is not calculated anymore if you are sorting the
results on any field, but only if you are not sorting on anything.
But that can be fixed quite easily by calculating the score yourself:
I wrote a blog post that explains how:

scroll to the "Performing queries" section of the post

Floyd -
There is a change in 2.9 where the score for a document is calculated
only if there is not a sort on a field.

I am current upgrade to 2.9.1 and also found that 2.9.1 perform better
when
sorting result than 2.3 and 2.4.
But I didn't find any change log about this performance enhancement.
(Can someone tell me about this issue?)

Art,
Thanks for the info. I'll give 2.9 a try.
I am pretty new to Lucene and I am wondering if there is an official channel
to find out which version is stable enough. I can't find anything on the web
site.

Hans,
We use 2.9 in production and we find it stable. 2.9 is indeed quite
recent so if in doubt, grab 2.4 tag.
