Subject [jira] Updated: (LUCENE-2023) Improve performance of SmartChineseAnalyzer
Date Sun, 08 Nov 2009 09:49:32 GMT

     [ https://issues.apache.org/jira/browse/LUCENE-2023?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Robert Muir updated LUCENE-2023:
--------------------------------

    Fix Version/s:     (was: 3.0)
                   3.1

if no one objects I'd rather work this into 3.1, along with some refactoring of this code.

DM Smith, if this causes you a problem I would rather just upload a java 1.4 patch for you
to improve your performance than slip it into 3.0.  there was already a bug in 2.9 in this
analyzer so I don't want to introduce a new one without having a lot of time to play with
this code.

> I've noticed SmartChineseAnalyzer is a bit slow, compared to say CJKAnalyzer on chinese
text.
> This patch improves the internal hhmm implementation. 
> Time to index my chinese corpus is 75% of the previous time.
