> Key: LUCENE-2644
> URL: https://issues.apache.org/jira/browse/LUCENE-2644
> Project: Lucene - Java
> Issue Type: Bug
> Components: Analysis
> Affects Versions: 3.0.2
> Reporter: Scott Gonyea
> Fix For: 3.0.3, 3.1, Realtime Branch, 4.0
>
> Attachments: LowerCaseTokenizer.patch
>
>
> While I understand some of the reasons for its design, the original LowerCaseTokenizer should have been named LowerCaseLetterTokenizer.
> I feel that LowerCaseTokenizer makes too many assumptions about what too tokenize, and I have therefore patched it. The *default* behavior will remain as it always has--to avoid breaking any implementations for which it's being used.
> I have changed LowerCaseTokenizer to extend CharTokenizer (rather than LetterTokenizer). LetterTokenizer's functionality was merged into the default behavior of LowerCaseTokenizer.
> Getter/Setter methods have been added to the LowerCaseTokenizer Class, allowing you to turn on / off tokenizing by white space, numbers, and special (Non-Alpha/Numeric) characters.
