[jira] [Commented] (LUCENE-6138) ItalianLightStemmer doesn't apply
on words shorter then 6 chars in length
[ https://issues.apache.org/jira/browse/LUCENE-6138?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14258906#comment-14258906 ]

> Key: LUCENE-6138
> URL: https://issues.apache.org/jira/browse/LUCENE-6138
> Project: Lucene - Core
> Issue Type: Bug
> Components: modules/analysis
> Affects Versions: 4.10.2
> Reporter: Massimo Pasquini
> Priority: Minor
>
> I expect a stemmer to transform nouns in their singular and plural forms into a shorter common form. The implementation of the ItalianLightStemmer doesn't apply any stemming to words shorter then 6 characters in length. This leads to some annoying results:
> singular form | plural form
> 4|5 chars in length (no stemming)
> alga -> alga | alghe -> alghe
> fuga -> fuga | fughe -> fughe
> lega -> lega | leghe -> leghe
> 5|6 chars in length (stemming only on plural form)
> vanga -> vanga | vanghe -> vang
> verga -> verga | verghe -> verg
> I suppose that such limitation on words length is to avoid other side effects on shorter words not in the set above, but I think something must be reviewed in the code for better results.
