public sealed class JapaneseKatakanaStemFilter : TokenFilter, IDisposableRemarks
Note that only full-width katakana characters are supported. Please use a CJKWidthFilter to convert half-width katakana to full-width before using this filter.
In order to prevent terms from being stemmed, use an instance of SetKeywordMarkerFilter or a custom TokenFilter that sets the IKeywordAttribute before this TokenStream.
