[jira] Commented: (LUCENE-1966) Arabic Analyzer: Stopwords list
needs enhancement
[ https://issues.apache.org/jira/browse/LUCENE-1966?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12763774#action_12763774 ]
Robert Muir commented on LUCENE-1966:
-------------------------------------
Basem, thanks for the patch, and the comments.
One thing I noticed: if I apply the patch, على (the stopword) will not be filtered as a stopword. This is because it will be normalized to علي (the name).
So, if we are going to normalize before stopfilter, I think we need to make sure the stopwords do not contain yeh without dots, or else these will not work. This is one example of why I was scared to apply normalization before stopwords, because by doing so, we cause على and علي to conflate.
Let me know what you think about this.
