Hiroaki Kawai commented on LUCENE-1216: --------------------------------------- The reason of setWhitespaceDelimiter(): Of cource we can call addDelimiter(' '), but it is usually insufficient. Whitespace chars we think, is described as: - It is a Unicode space character (SPACE_SEPARATOR, LINE_SEPARATOR, or PARAGRAPH_SEPARATOR) but is not also a non-breaking space ('\u00A0', '\u2007', '\u202F'). - It is '\u0009', HORIZONTAL TABULATION. - It is '\u000A', LINE FEED. - It is '\u000B', VERTICAL TABULATION. - It is '\u000C', FORM FEED. - It is '\u000D', CARRIAGE RETURN. - It is '\u001C', FILE SEPARATOR. - It is '\u001D', GROUP SEPARATOR. - It is '\u001E', RECORD SEPARATOR. - It is '\u001F', UNIT SEPARATOR. http://java.sun.com/javase/6/docs/api/java/lang/Character.html#isWhitespace(char) I thought the white space chars are so many that it is hard to register each time. > CharDelimiterTokenizer > ---------------------- > > Key: LUCENE-1216 > URL: https://issues.apache.org/jira/browse/LUCENE-1216 > Project: Lucene - Java > Issue Type: Improvement > Components: Analysis > Reporter: Hiroaki Kawai > Assignee: Otis Gospodnetic > Priority: Minor > Attachments: CharDelimiterTokenizer.java, > CharDelimiterTokenizer.java, TestCharDelimiterTokenizer.java > > > WhitespaceTokenizer is very useful for space separated languages, but my > Japanese text is not always separated by a space.
