Examples of org.apache.lucene.analysis.LowerCaseTokenizer

org.apache.lucene.analysis.LowerCaseTokenizer
LowerCaseTokenizer performs the function of LetterTokenizer and LowerCaseFilter together. It divides text at non-letters and converts them to lower case. While it is functionally equivalent to the combination of LetterTokenizer and LowerCaseFilter, there is a performance advantage to doing the two tasks at once, hence this (redundant) implementation.
Note: this does a decent job for most European languages, but does a terrible job for some Asian languages, where words are not separated by spaces.
