[jira] [Updated] (LUCENE-4072) CharFilter that Unicode-normalizes
input
[ https://issues.apache.org/jira/browse/LUCENE-4072?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
David Goldfarb updated LUCENE-4072:
-----------------------------------
Attachment: LUCENE-4072.patch
I'm available to help make this work. I updated [~ippei]'s code to use 4.0 API (CharStream, CharReader, ReusableAnalyzerBase affected). I updated [~rcmuir]'s random input test and it's not failing. I'm not sure if Ippei's last fix worked and this ought to have been closed then. I don't see this class in the Lucene library.
Let me know if this helps.

> I'd like to contribute a CharFilter that Unicode-normalizes input with ICU4J.
> The benefit of having this process as CharFilter is that tokenizer can work on normalised text while offset-correction ensuring fast vector highlighter and other offset-dependent features do not break.
> The implementation is available at following repository:
> https://github.com/ippeiukai/ICUNormalizer2CharFilter
> Unfortunately this is my unpaid side-project and cannot spend much time to merge my work to Lucene to make appropriate patch. I'd appreciate it if anyone could give it a go. I'm happy to relicense it to whatever that meets your needs.
