Subject [jira] Commented: (SOLR-1336) Add support for lucene's SmartChineseAnalyzer
Date Wed, 16 Sep 2009 18:59:57 GMT

    [ https://issues.apache.org/jira/browse/SOLR-1336?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12756177#action_12756177

Stanislaw Osinski commented on SOLR-1336:
-----------------------------------------

Keeping the Chinese analyzer JAR optional sounds good. As Carrot2 also uses it, I'd need to
make sure the clustering contrib doesn't fail when the JAR is not there and clustering in
Chinese is requested (I think I'd simply log a WARN saying that the Chinese analyzer JAR is
required for best clustering results).

> 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.
