             Summary: Removing grave accent in Dutch Snowball algorithm
                 Key: LUCENE-9295
                 URL: https://issues.apache.org/jira/browse/LUCENE-9295
             Project: Lucene - Core
          Issue Type: Improvement
            Reporter: Nguyen Minh Gia Huy


I have a concern on how [Dutch Snowball algorithm|http://snowball.tartarus.org/algorithms/dutch/stemmer.html] handles the grave accent of *è.*

It removes the grave accents on *{{à}}*, {{*ò*}}, *{{ù}}*, *{{ì}}* but doesn't with *è*. I wonder if there is something special with *è* that the stemmer wants to ignore it. 

Also, from [http://www.dutchgrammar.com/en/?n=SpellingAndPronunciation.25,] I found out that grave accent is not used commonly in Dutch anymore except in some borrowed French words. 

If *è* is not that common in Dutch, removing grave accent on it sounds reasonable to me and definitely benefits search recall in general.

I would like to know if anyone had a strong opinion on this topic ? It would also nice if you have some point of views as a  Dutch speaker.

Thanks !
