Filters StandardTokenizer with StandardFilter, LowerCaseFilter, StopFilter and SnowballFilter. Available stemmers are listed in org.tartarus.snowball.ext. The name of a stemmer is the part of the class name before "Stemmer", e.g., the stemmer in EnglishStemmer is named "English".

• As of 3.1, uses TurkishLowerCaseFilter for Turkish language.
