public final class HindiNormalizationFilter

A TokenFilter that applies HindiNormalizer 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 KeywordMarkerFilter or a custom TokenFilter that sets the KeywordAttribute before this TokenStream.
