A RussianLetterTokenizer is a Tokenizer that extends LetterTokenizer by also allowing the basic Latin digits 0-9.
You must specify the required Version compatibility when creating RussianLetterTokenizer:
- As of 3.1, CharTokenizer uses an int based API to normalize and detect token characters. See CharTokenizer.isTokenChar(int) and CharTokenizer.normalize(int) for details.
