@Deprecated
public final class DutchStemFilter
- extends TokenFilter
A TokenFilter
that stems Dutch words.
It supports a table of words that should
not be stemmed at all. The stemmer used can be changed at runtime after the
filter object is created (as long as it is a DutchStemmer
).
To prevent terms from being stemmed use an instance of
KeywordMarkerFilter
or a custom TokenFilter
that sets
the KeywordAttribute
before this TokenStream
.
