In Turkish alphabet lowercase of I is not i. It is LATIN SMALL LETTER DOTLESS I. LowerCaseFilter which uses Character.toLowerCase() makes mistake just for that character.
http://java.sun.com/javase/6/docs/api/java/lang/String.html#toLowerCase() I am not sure if it is worth to add a new TokenFilter for Turkish language. I see there exist GreekLowerCaseFilter and RussianLowerCaseFilter. It would be nice to see TurkishLowerCaseFilter in Lucene. Wiki recommends to ask permission from lucene committers before opening an issue. I can provide a patch (although it is just a one line change in original LowercaseFilter) for that if you want. Thank you for your consideration.
