public final class BengaliNormalizationFilter
extends TokenFilter

A TokenFilter that applies BengaliNormalizer to normalize the orthography.

In some cases the normalization may cause unrelated terms to conflate, so to prevent terms from being normalized use an instance of SetKeywordMarkerFilter or a custom TokenFilter that sets the KeywordAttribute before this TokenStream.
