[ https://issues.apache.org/jira/browse/SOLR-1336?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12749859#action_12749859 ]
Kumar Raja commented on SOLR-1336:
----------------------------------
I applied the patch with the latest Solr code and lucene-rc2 jars and tried indexing the some chinese text. However, i got a AbstractMethodError during tokenization.
What am i doing wrong here?

> Add support for lucene's SmartChineseAnalyzer
> ---------------------------------------------
>
> Key: SOLR-1336
> URL: https://issues.apache.org/jira/browse/SOLR-1336
> Project: Solr
> Issue Type: New Feature
> Components: Analysis
> Reporter: Robert Muir
> Attachments: SOLR-1336.patch, SOLR-1336.patch
>
>
> SmartChineseAnalyzer was contributed to lucene, it indexes simplified chinese text as words.
> if the factories for the tokenizer and word token filter are added to solr it can be used, although there should be a sample config or wiki entry showing how to apply the built-in stopwords list.
> this is because it doesn't contain actual stopwords, but must be used to prevent indexing punctuation...
> note: we did some refactoring/cleanup on this analyzer recently, so it would be much easier to do this after the next lucene update.
> it has also been moved out of -analyzers.jar due to size, and now builds in its own smartcn jar file, so that would need to be added if this feature is desired.
