Subject [jira] Commented: (SOLR-1336) Add support for lucene's SmartChineseAnalyzer
Date Sat, 08 Aug 2009 22:25:14 GMT

    [ https://issues.apache.org/jira/browse/SOLR-1336?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12740988#action_12740988
] 

Robert Muir commented on SOLR-1336:
-----------------------------------

{quote}
Are the stopwords (words="org/apache/lucene/analysis/cn/stopwords.txt") being loaded directly
from the jar? If so, a comment to that effect might prevent some confusion. 
{quote}

Yes, good idea.

{quote}
Do you happen to know what the memory footprint of this analyzer is if it's used? I assume
the dictionaries will get loaded on the first use.
{quote}

No, I am not sure of the footprint, but it is probably quite large (a few MB). They will be
loaded on first use, correct. Also, the smartcn jar file itself is large due to the dictionaries
in question. So, you may have noticed solr.war is much smaller after the last lucene update,
since it was factored out of analyzers.jar.

Might be cool to add a chinese field to example/exampledocs/solr.xml... or maybe there should
be an international.xml doc where we could add a few different languages?
{quote}

I figured this wasn't the best place to have an example... i like the idea of international.xml,
with some examples for other languages too.

If there is some concern about the size of this (monster) analyzer, one option is to put these
factories/examples elsewhere, to keep the size of solr smaller.

> 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.
