Lowercase Tokenizer
editLowercase Tokenizer
editA tokenizer of type lowercase that performs the function of
Letter
Tokenizer and
Lower
Case Token Filter together. It divides text at non-letters and converts
them to lower case. While it is functionally equivalent to the
combination of
Letter
Tokenizer and
Lower
Case Token Filter, there is a performance advantage to doing the two
tasks at once, hence this (redundant) implementation.
