    public final class SimpleAnalyzer

extends ReusableAnalyzerBase

An `Analyzer` that filters `LetterTokenizer` with `LowerCaseFilter`

You must specify the required `Version` compatibility when creating `CharTokenizer`:

- As of 3.1, `LowerCaseTokenizer` uses an int based API to normalize and detect token codepoints. See `CharTokenizer.isTokenChar(int)` and `CharTokenizer.normalize(int)` for details.
