## org.apache.lucene.analysis.ar
Class ArabicLetterTokenizer

    java.lang.Object

                          org.apache.lucene.analysis.ar.ArabicLetterTokenizer

All Implemented Interfaces:
  Closeable

Deprecated. (3.1) Use `StandardTokenizer` instead.

    @Deprecated
    public class ArabicLetterTokenizer

extends org.apache.lucene.analysis.LetterTokenizer

Tokenizer that breaks text into runs of letters and diacritics.

The problem with the standard Letter tokenizer is that it fails on diacritics. Handling similar to this is necessary for Indic Scripts, Hebrew, Thaana, etc.

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

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