Subject [jira] [Updated] (LUCENE-3888) split off the spell check word and surface form in spell check dictionary
Date Sat, 24 Mar 2012 06:19:23 GMT

     [ https://issues.apache.org/jira/browse/LUCENE-3888?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Koji Sekiguchi updated LUCENE-3888:
-----------------------------------

    Attachment: LUCENE-3888.patch

I added a test for the surface analyzer. I also added code for the analyzer in Solr.

Currently, due to classpath problem, the test cannot be compiled. I should dig in, but if
someone could, it would be appreciated.

> The "did you mean?" feature by using Lucene's spell checker cannot work well for Japanese
environment unfortunately and is the longstanding problem, because the logic needs comparatively
long text to check spells, but for some languages (e.g. Japanese), most words are too short
to use the spell checker.
> I think, for at least Japanese, the things can be improved if we split off the spell
check word and surface form in the spell check dictionary. Then we can use ReadingAttribute
for spell checking but CharTermAttribute for suggesting, for example.
