Subject [jira] Commented: (LUCENE-2023) Improve performance of SmartChineseAnalyzer
Date Fri, 30 Oct 2009 18:37:59 GMT


DM Smith commented on LUCENE-2023:

Thanks, Mark.

I'm stuck with 1.4 for the near future. :( I wish people would upgrade their MacOS! I'll have
a release soon and then another in 4-6 months. The release after that will be Java 5 and will
probably follow shortly after.

I'm willing to do the work, especially if it is trivial and it is something I use:) Perhaps,
it would be best to create a separate issue targeting 2.9.2 (or whatever the next release
might be), linking it to the original(s), mark it as an "Improvement" and attach appropriate
patch(es). Maybe one issue for all improvements, or one per "parent" issue? Then if there
is a bugfix that necessitates such a release, the patches would be applied for that release.
