[jira] [Commented] (LUCENE-4072) CharFilter that Unicode-normalizes
input
[ https://issues.apache.org/jira/browse/LUCENE-4072?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13280687#comment-13280687 ]
Robert Muir commented on LUCENE-4072:
-------------------------------------
This looks cool: it looked tricky to me to implement that iterative normalization api, I'm glad you tackled it :)
Its a good idea, for some tokenizers like Ngrams etc you really need normalization as a charfilter.
I'll see if i can help with the integration.
> CharFilter that Unicode-normalizes input
> ----------------------------------------
>
> Key: LUCENE-4072
> URL: https://issues.apache.org/jira/browse/LUCENE-4072
> Project: Lucene - Java
> Issue Type: New Feature
> Components: modules/analysis
> Reporter: Ippei UKAI
>
> 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.
